Are you OK with who you are ? Or do you think that all of your work is in vain and you blame yourself for not having the expected results ?
It doesn't sound good but it happens. It's hard to think that you won't never be able to do what you want the most. As for me, I say that everything that happens is for a reason and this is the way that things should be. We can't be the ones responsible for everything that we don't have the chance to do.
