It's never too late to be whoever you want to be.

"You can be mad as a mad dog at the way things went, You can swear and curse the fates, but when it comes to the end, you have to let go."
"It's never too late to be whoever you want to be. There's no time limit - start whenever you want. You can change or stay the same there are no rules to this thing. We can make the best or the worst of it, I hope you make the best of it. I hope you see things that stop you, I hope you feel things you've never felt before, I hope you meet people with a different point of view, I hope you live a life you're proud of - and if you find that you're not I hope you have the strength to start all over again. "
