If you are questioning your motivations it shows that you are maturing. A lot of people would not understand someone like you who is thinking about the best way to spend your time and what you "really" want to do with your time and life.
College is the time to do this...and only you "really" know your own level of skills.
But let me just say that the underlying assumption of your question implies that the only reason to play college baseball is to prepare to get to the next level or the pros. And what I'm going to say to you may be controversial but, playing baseball to make it to the pros is totally a wrong way of looking at this activity.
Most of the players playing right now will not make it to the pros.
Then why play you ask, ......because it trains you to deal with boredom and humility....the two most difficult aspects of human behavior to concur.
Those who don't understand that aspect of baseball's real benefit fall prey to the consequences of their own lack of understanding of it.
In doing so, many students allow that lack of understanding to be used as an excuse to fail, both academically and athletically.
If you're wrestling with how to deal with boredom and humility, don't quit baseball.
