My persistence

Some things can only happen when we are persistent enough letting them happen. Just like sincerity can move mountains, persistence can make miracles happen. Sometimes, I feel that certain things can only be seen if I persist and never give up. I did it once, I persisted in doing that one thing, it was nearly impossible to be done, yet I never gave up. I have failed times and times, but it was something I really needed,maybe that's why I could not give up easily. That was the one time I remember clearly that my persistence and first of all God allowed it to happen. I wonder if all things I dream of would be placed before my eyes if I had the enough determination and persistence to let them happen? Am I not doing my very best and instead making enough excuses for my heart to move on quickly and give up? What if I persist on this one thing again? What if I never give up once more?
