Gift-Marcus Aurelius

Each day provides its own gifts.

Quote from Seven Years in Tibet

If a problem can be solved there is no use worrying about it.

Advise from Anthony Robbins

Live life fully while you're here. Experience everything. Take care of yourself and your friends. Have fun, be crazy, be weird. Go out and screw up!

Don't try to be perfect; just be an excellent example of being human.
