Today is the right day to be unselfish and put others before yourself. You will reap your rewards at a later time.
You are not afraid of putting yourself first, but today is the right day to put others ahead of you. It's not going to be too much skin off your nose, but it will mean a lot to the people you help out and prioritise. You may need to let your own needs and plans slide a little, but this unselfish act is going to come back to you ten-fold at a later time. Also, you will feel great about yourself.
