I finally understand the full meaning of that phrase.
I've been standing in my own way. When something is difficult and many things seem to bar me from my intended destination I feel daunted, and eventually turn my sights onto a different course....That mentality has hindered me more than it has ever aided me.
If you desire something, truly want it, then nothing will stand in your way. Yes, there will be complications, but you have to overcome them. If you will not fight the obstacles with every part of your being then you've defeated yourself.
You must make yourself keep fighting; the moment you doubt is the moment you cease to be able to push forward.
