My favourite ever quote...
"I do my thing, and you do your thing. I am not in this world to live up to your expectations, and you are not in this world to live up to mine. You are you, and I am I, and if by chance we find each other, it's beautiful."
Frederik E. Perl
And also another one which is very simple, but very inspirational to me at various times in my life..
"My answers unspoken of sweetest emotion
Believe how it feels today
Just believe how it feels today
Oh, I was told by a knight of the sun
That wisdom could set people free
Be content in your questions
And may I just mention
You're only a drop in the sea
Only a drop in the sea"
No, not a renowned poet or author, but Crispian Mills of Kula Shaker
