Post-It Notes should be filled with such friendly reminders from time to time - make sense and worth remembering:
Don't compare your life to others'. You have no idea what their journey is all about.
Don't take yourself so seriously; no one else does!
Envy is a waste of time. You already have all you need.
Forget issues of the past. Don't remind your partner with his/her mistakes of the past. That will ruin your present happiness.
Life is too short to waste time hating anyone. Don't hate others.
Make peace with your past so it won't spoil the present.
No one is in charge of your happiness except you.
Realize that life is a school and you are here to learn. Problems are simply part of the curriculum that appear and fade away like algebra class, but the lessons you learn will last a lifetime.
You don't have to win every argument. Agree to disagree.
Forgive everyone for everything.
Spend time with people over the age of 70 and under the age of 6.
What other people think of you is none of your business.
Your job won't take care of you when you are sick. Your family and friends will. Stay in touch.
However good or bad a situation is, it will change.
The best is yet to come.
