Growth!

As many great minds have said, "It is only a fool that never changes his mind." As you grow, you understand how trivial some things are in the specifications and or perspectives of a huge lens. 

You embrace those you perhaps, faulted and chastise yourself for being young and unwise and vice versa. You accept that you aren't just human but they are too. You respect people's efforts at their own growth within their own paces just as you allow yourself to mature in your ways.

Yes, mistakes do not define you but they should shape your thoughts and deeds. They are mistakes purely for humane reasons. Allow yourself and others to grow.

And while you are still striving to be an awesome being, find what gives you peace and enjoy your life.
