Entrepreneur Jim Rohn once said, “The twin killers of success are impatience and greed.”

It is like he was talking about fantasy baseball owners when he said it.

Owners draft players like Mike Trout, Clayton Kershaw, Aaron Judge and Giancarlo Stanton expecting immediate results and peak performance from the first pitch of the season until the last. It is greedy and unrealistic thinking. The second those players do anything besides what is expected of them, panic begins to set in.

Sometimes players comes out of the gate moving as fast as Bartolo Colon running to a gym. This is where you have to remember the fantasy baseball season is a marathon (a long marathon), not a sprint.

Take, for instance, Mark Teixeira. He was historically a slow starter, hitting .235 in 269 career games in March/April, but he hit .282 in July and .281 from August-October. He did what was expected of him when he was needed the most.

You drafted Trout, Judge and the other stars because they’re reliable when you need them. If they get off to slow starts, it isn’t time to start making trade offers (but, it is when you take advantage of the dope making the offers). If a player starts slow, be patient.

George Springer not only became the first player to hit a leadoff home run for a defending World Series champion, he also is the only player to hit a leadoff homer on Opening Day in consecutive years, according to Elias Sports Bureau.

As impressive as those feats are, March/April historically have not been kind to Springer — he has hit just .229 over 127 games. The only month he has been worse is August. The first month of the season has also brought his worst on-base percentage (.302) and his second-worst slugging percentage (.440), OPS (.742) and runs scored production (74).

Springer, however, turns things around quickly, hitting .288 in May, .293 in June and .332 in July.

There are others who have a history of struggling early, such as Edwin Encarnacion. He never seems to get it going until June, hitting .240 in March/April and .247 in May (despite bashing 118 homers and driving in 360 RBIs over 594 career games in those months). March-May is also when he has his lowest average, highest strikeout total and his lowest OBP, SLG and OPS.

Justin Verlander picked up a win in the opener, but March/April is the only “month” he has a losing record (22-24) and an ERA above 3.67 (he is at 3.98). He tends to be at his best in June (31-13) and, when it matters most, in September/October, when he is 43-17 with a 2.89 ERA.

Brian Dozier has his worst average (.225), slugging percentage (.366) and OPS (.676) in April, and Jason Kipnis is a .228 hitter with a .642 OPS before hitting .291 in May and .295 in June.

Kershaw is un-Kershaw-like during the first month, going 20-14 with a 2.85 ERA in 48 career starts. By comparison, he is 31-6 with a 1.62 ERA in 48 July starts.

Corey Kluber has a losing record (11-12), his highest ERA (4.00) and lowest strikeouts per nine (9.2) of any other month, and Jose Quintana is 10-16 with a 4.36 ERA to kick off the season.

Rick Porcello went 5-0 with a 2.76 ERA in April during his 2016 Cy Young campaign, but that was an anomaly, as he is 19-23 with a 5.25 ERA and 1.404 WHIP in 52 career appearances (51 starts).

You also have to make sure you don’t get too caught up in players who get off to red-hot starts. Just because the White Sox’s Matt Davidson smashed three homers in the opener doesn’t mean he is going to be the next Stanton. It just means he is worth keeping an eye on, or riding them while hot. Remember Eric Thames last year? Trevor Story in 2016?

If highly prized youngsters such as Matt Olson, Rhys Hoskins, Rafael Devers, Luke Weaver, Shohei Ohtani, Blake Snell or Luis Castillo get off to slow starts, it doesn’t mean you should abandon ship. You targeted them in drafts as building blocks for the future. There isn’t a lot of history to go on with these players, so give them time.

Patience is a virtue for a reason. Don’t forget that.

Scott Kingery 2B, Phillies

Speedy top prospect went 23-for-56 (.411) with five homers, eight RBIs, four stolen bases and a 1.226 OPS this spring. The 23-year-old was the most added player in ESPN leagues this week.

Patrick Corbin SP, Diamondbacks

Maybe the newly installed humidor in Chase Field will help bring down his career 4.12 ERA, because he was the most added starting pitcher in ESPN leagues this week.

Ian Happ 2B/OF, Cubs

Hit seven spring homers, tied with three others for the most in the league. He continued flex his muscles on Thursday, hitting the first pitch of the season out of the park.

Blake Snell SP, Rays
After going 5-2 with a 3.49 ERA in the second half of 2017, the lefty picked up where he left off. He struck out 27 in 17 ¹/₃ innings, walked just five and maintained a 3.12 ERA this spring.

Chad Kuhl SP, Pirates

If there was an award for least effective spring training pitcher, it could go to the 25-year-old righty — who went 1-2 with a 10.06 ERA, five homers allowed, nine walks and a 2.059 WHIP.

Mike Leake SP, Mariners

Allowed the most hits (36) in the majors this spring en route to a 5.40 ERA and a .356 opponent average. Luckily, he plays in a pitcher-friendly park.

Homer Bailey SP, Reds

The veteran went 0-2 with a 7.50 ERA, allowing 15 earned runs, seven homers and a .338 opponent average. Amazingly, that earned him the Opening Day start.

Drew Robinson OF, Rangers

He hit .190 with 26 strikeouts (the most in the majors) and a .278 OBP in 63 spring at-bats. And, yes, he was on the Opening Day roster.

— The lowest opponent average for qualified pitchers this spring: Roto Rage favorite Zack Godley, who allowed a .134 average over 20 ¹/₃ innings for the Diamondbacks. Clayton Kershaw had the second lowest with .162. What does that mean? Well, nothing. It’s spring training. It means about as much as the excuses you used to give your teachers when you didn’t do your homework.

— Astros outfield prospect Kyle Tucker led the majors with 21 RBIs this spring. The 21-year-old is starting the season in Triple-A, so that is your Kyle Tucker update for the season.

— Salvador Perez sprained the MCL in his left knee while carrying a suitcase up a flight of stairs. This goes down with other dumb injuries, like Sammy Sosa landing on the DL with a back injury after sneezing, or Kevin Mitchell being late to spring training in 1990 after burning the top of his mouth with a microwaved donut, or Trevor Bauer slicing his pinky finger while repairing a drone. See ya in 4-6 weeks, Sal.
