I've been given a few.
Pick your fights carefully. If you fight everyone you'll have no time to enjoy your life.
Life is all about change, sometimes is beautiful, sometimes it's painful. Your first big loss (of a loved one) is important, as it leaves you better prepared for the next.
Accepting that you will fail is OK. If a task is beyond you, like jogging to the moon. Don't worry about, accept that you will fail.
If someone told you a something that could have serious consequences if word got out, like knocking someone down and killing them on the road and not stopping, could you take that secrete to the grave with you?
