Self-Esteem
Write a list of things about yourself of which you are proud. When you have a bad day, refer to the list to help you remember how important you are.
Self-Defense
Learning self-defense can help you fulfill the mitzvah of pikuach nefesh, saving a life (including your own)
Dedication for Self
Let the holiday of Chanukah be an inspiration to dedicate yourself to include more Jewish learning in your daily life.
Self-Reflection
On the last night of Chanukah (tonight), take extra time enjoying the menorah lights and thinking about how the ideas of miracles and salvations apply to your own life.
Donation From Self
Many Jewish organizations love to receive donations of people's volunteer time.
