Okay, so if my goal is to throw hard and dominate my friends, I'm going to take strides to build up arm strength, hit my spots, and even change speeds, right? I'm going to try to do that and if I reach my goal, I'll just barely reach it and probably require maintaining that level if I want to keep making my friends look like fools in the batter's box.
And that's fine.
But if I did set a higher goal of making it to the majors (or, for me, an equally impossible goal of making it to a minor league tryout), I'd go above and beyond, in hopes of striking out professional hitters, and wind up a tougher pitcher, right? Even inevitably falling short, I come out ahead.
If your goal is making it to the majors,
and you have a plan and willingness to execute to that plan, you'll spend basically every waking minute not spent doing your day job to get there. You will quite literally eat, sleep, and sh!t baseball 24/7. You'll devote hours and hours in the gym, time [and money] with pitching coaches, personal trainers, nutrition planning, etc.
You won't have to worry about throwing hard and dominating your friends, because if you're putting that much time in, you won't see them for years anyway.
Now... What if you don't have the physical talent to throw in the majors, or even AAA ball? If that's the case [and just playing the odds I'm guessing it is], then why would you bother executing a plan to get you there? You're not willing to spend $5 on a lotto ticket, which has better odds than you suddenly finding athletic talent that doesn't exist. My advice to you would be to not even start on executing your plan, because the opportunity cost of what you could be doing with that time and money is much higher doing almost anything else.
Of course, let's say your goal is to make it to the majors, and your plan only entails 50% more work than what it'll take to dominate your friends rather than hyper-focused dedication. Well, that's a crappy plan that doesn't have the dedication and effort needed to get to the majors. If that's your plan, then I'd say you don't really believe in, or want, to reach your goal, because your plan won't do it even if you execute. Your goal is a fantasy at that point.
I'm 42. You can qualify for the PGA senior tour at 50. That's 8 years. I think in the back of my head "what if I started now and really tried to make it?" But I'm not going to, because the amount of work needed to get there is more than I'm willing to put in on golf. So if I said my goal is to make the senior tour in 8 years, and you looked at how hard I'm working towards it, you'd realize that the goal is not attainable with that level of work. So it's just a fantasy, not a goal.
