Want to know another trick to happiness?
Try doing this gratitude exercise!
At the end of each day, write down one thing (or more!) that you are grateful for from that day. It can be as simple as that nice man who held the door for you, or as significant as your mentor who guided you in your work. Try it, and you will find yourself feeling better about your life!
Today I am grateful for my PhD advisor for being a great mentor (I was writing a recommendation letter for his tenure process and recalled all the things he has done for us in the lab). The other day, I was grateful for my aunt who taught me the meaning of zen and altruism.
What are you grateful for today? =)
