People give too much credit to the idea of fate. While some things are certainly by chance and out of your control, many others come down to choice personal responsibility. If you want to keep people in your life, treat them well.
"In the end we only regret the chances we didn't take." So be risky because you would rather look back and say I can't believe I did that instead of I can't believe I didn't do that. I do regret that amazing chance that I didn't take.
