When it's God-given, no man can take it away. Trust the process. Every time I thought I lost, it turned into an opportunity to get better. It taught me that what is for me shall be for me. Often times we make opportunities out to be losses, focusing on the wrong things. Better in these times, to stay away from what you think went wrong and focus only on what is STILL going right, that way you'll always have something to work with.
Winners aren't "lucky", we just learn to work with what we have. In any situation. Remember, failure isn't final, unless you want it to be. In fact, we couldn't survive without it. It is necessary for growth.
