Imposter syndrome is not a problem.
Every player who moves up a level in baseball has imposter syndrome. Every. Single. One.
The D1 commit who arrives on campus wondering if he belongs. The SEC guys who get there and realize for the first time that things are actually hard. I've seen high school legends playing junior college ball after one season in the SEC.
Imposter syndrome is universal. It is not a unique problem.
There was a player I played with who showed up on day one of summer ball and looked completely ordinary in the cage. Nothing about his swing said he would be a first rounder. On opening day, he went 4-4 to my surprise. And two months later, if he didn't get multiple hits, I was shocked. This player was hitting everything. Nobody could get him out. Nothing fancy about Zach Neto. Just consistent success.
You are what you do. It did not matter what he looked like on day one.
Here is the rule I tell players: if you stay late at practice once, you are a "tryhard". You stay late for a week, people think it is a phase. You stay late for three months, you are the guy who stays late. After a year, people come to you when they also want to hit after practice. After three years, you are a resource, teammates seek you out for your help.
All you did was stay late and hit extra.
The same thing goes for being late. You show up late twice and you are the guy who is always late. Bad labels stick faster than good ones. That is just how it works.
A D1 commit is not who you are. It is recognition for who you were. The players who make it are the ones who figure out that distinction.
I was undersized and worked hard because I did not know enough to think I should quit. That stupidity turned into a process. The process turned into a D1 career.
You do not need to solve imposter syndrome. You need a process you trust more than the feeling of being an "imposter".
If you want help building that process, Athora Lab's development resources are written by guys who did it the hard way and figured out what actually works.
Decide who you want to be. Then do that every day. The rest follows.
