Failure only happens when you lose your willpower to continue trying...If we let the obstacles get the best of us then it was our choice to fail, not fate.
There isn't any questioning the fact that some people enter your life, at the exact point of need, want or desire - it's sometimes a coincendence and most times fate, but whatever it is, I am certain it came to make me smile.
Give your all to every experience, feel it breathe it appreciate it, nothing lasts forever, when it's gone you'll remember the feeling it once gave you and sometimes that's enough.
