If we think we can practice Buddhism and that this practice will change everyone in our lives to become agreeable or likeable or be some way that suits us, then we are working the wrong end of the formula. Buddhism is about changing ourselves, which in turn causes our environment to change. The formula is change in self equals change in others and environment. The formula is not changing environment will change oneself. This is important to always keep in mind. The most effective thing to work on to become happy, to become enlightened, is one’s own life.
