I can look back at all my mistakes and feel buried, or I can be proud that I went for it. Regret mainly lives in the memory of a missed opportunity, inaction, our unlived life, and a forever lost moment. – Lori Todd

Anyone who has never made a mistake has never tried anything new. – Albert Einstein

It is not the things we do in life that we regret on our death-bed. It is the things we do not. All the mistakes, and all the dopey things, and all the times I was embarrassed — they don’t matter. What matters
is that I can look back and say: Pretty much any time I got a chance to do something cool I tried to grab
for it — and that’s where my solace comes from. – Randy Pausch (May 2008, 3 months before he died)

A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing.
– George Bernard Shaw
