If you don't feel worthy of achieving the goal you set, it won't matter how hard you work or how much time you put into getting there. You'll always find ways to delay achieving the goal and the worst part is, if you don't see what's happening, you'll think you are failing. You'll think that you aren't capable of achieving your goal because you're flawed, you aren't smart enough, you aren't disciplined enough, but the realty is that subconsciously a part of you is working to undo all of the work you do.
