My favourites change with my mood. I guess current favourite saying is
grant me the serenity to accept the things I cannot change and give me the courage to change the things I cannot accept. And wisdom to know the difference.
And despite quoting this at random to someone who really ought to take heed, it ain't going in!!!!!!!!
Come on, change your mind
You never know what you might find
Break out the rizlas
And roll up a place to unwind
Well you can bust me once
You can bust me twice
But you'd have to top me
To finally stop me from loading my dice
