A friend shared this list with me, which I think is pretty wonderful.
Make your bed every day.
Pray. Pray always. This is the mastery of thoughts.
Be kind to everyone. Especially yourself.
Study and ponder the scriptures first thing in the morning.
Find ways to talk about and live what you study each day.
Respond quickly to promptings.
Say I love you as often as possible and really mean it.
Look people in the eyes when they're talking to you.
Treat the one you are with as if they are the most important person in the world. In that moment, they are!
Take a good long look in the mirror every day. Be sure to make eye contact with yourself. AND don't pass judgment.
Look for hints of greatness in yourself and others. Vocalize it.
Feel the sun shine on your face for at least 10 minutes a day.
Never give up chocolate. Ever!
Try to listen more than you talk.
Remember that someone always has it worse than you. Get over yourself.
Laugh every single day. The harder the better.
Read a conference talk or Ensign article every day.
Never hold back a positive comment, compliment or thought. BUILD! BUILD! BUILD!
Trust that life is divinely guided and is happening exactly as it should be.
Say thank you.
Any other ideas to add?
