The hardest things for me to learn and accept have been:

• In relationships, being right is highly overrated.
  
• The universe doesn't care if I succeed or fail.
• The biggest obstacle I have to overcome in pursuing success is myself.
• I'm the sole owner of my thoughts and emotions.
• Other people seldom see me the way I think they do, or the way I want them to.
• I can't change you.
• Nobody owes me anything.
• I can't get the time back.
• I won't be here one day, and I have no idea when that day will come or how I'm going to exit this life.
