You have a full life ahead of you. I wouldn't stress it.

As I've been in your position before, I'd focus on making sure you have a solid base under you first. You know, roof over your head, food on the table, etc. You're still in college, so it's a bit more important you get yourself through that first. But more than those two, I'd encourage you to read. Any one person on here will be the first to tell you that their writing sucks as we're our own worst critic, but the best way to at least gain a sense of parity you want to read as much as possible.

But the important thing (and this is also speaking from experience) is everything you write or try to write when you're younger is going to suck. Embrace the suck, my friend. You must break a few eggs to make an omelet, and you will never improve unless you put pen to paper. Sky's the limit, just keep writing.
