I've learned that when I don't stop... ever... I will eventually win. The biggest key to success in any God-breathed endeavor is simply this - persevere - don't stop! Keep going! Keep pushing! Breakthrough is probably around the corner.
I certainly don't mean persevering by doing the same thing over and over again - they say that a form of insanity is doing the same things over and over and over again and expecting different results. No, I'm talking about tapping into your creativity. I'm talking about reading the word of God and reading loads of books and exploring the avenues by which your endeavor could form, gain momentum, and fly!
If your supposed to do something, there should be a deep 'knowing' inside of you, a deep peace. Allow a quiet (and sometimes loud and boisterous) resolve to take over. AND BY ANY AND ALL MEANS - DON'T YOU DARE STOP!
