Work at something you enjoy and that's worthy of your time and talent.
A friend is someone who knows you and loves you for what you were and who you are, and who also shares your hopes and dreams for who you can become.
Don't judge those who try and fail. Judge only those who fail to try.
Seek opportunity, not security. A boat in the harbor is safe, but in time its bottom will rot out.
Live and learn and pass it on.
When you are angry or frustrated, what comes out? Whatever it is, it's a good indication of what you're made of.
