Being that we never know when we will start "looking back". It is better to look back on life and say, "I can't believe I did that," than to look back and say, "I wish I did that." I want to make the Believe list longer than the wish list!
"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.
