Be kind - Don’t be soft, but be gentle. Don’t crawl over anyone on your way up, but don’t stop crawling up either.
Be patient - you know what you need to do. Do it and good things will happen.
Be quiet - if you’re great, people will know it; if you’re not, keep it to yourself.
Be happy - this is not easy. It takes some courage, oddly, simply to be happy.
Be the Serenity Prayer.
Be honest - just in case there is a God who is watching.
Love someone else.
Be silly - and if you have kids someday, let them listen to music that makes them happy. There are many, many ills that can be cured by a kid giggling and dancing in the backseat.
Oh…and don’t be preachy.
