Two great questions to ask yourself daily are:
1. What did I do to make someone else smile?
2. What did I do to make myself smile?
It is easy to say that making other people smile is your reason to smile. I don't believe that is enough.
You can live your life helping people but if you don't look out for your well being then you can fall into the trap of only identifying your happiness with the happiness of other people.
You can make your life about helping people but every day of your life is about you too.
Live vibrantly and unapologetically.
