Are you doing it for others? This is a notion inherent to certain faiths or practices.
When you take refuge as a Buddhist, you commit to saying the Bodhisattva vow, which basically states that you wish to continue being reborn until everyone is enlightened. Essentially, it is a repeated reminder to continue practicing, acting, and dedicating your practices and work to others. There are many people in the world and throughout history, such as Mother Theresa or Nelson Mandela, whose motivation for changing and connecting with the world was driven by service to others. Acting for others is another major driving factor—motivation—which can prove very powerful.
