I'm having a hard time with difficult unkind people and lifes' cruel lessons but I choose happiness

Every human being on the planet
 wants to be happy. Anything that anyone desires is because they think their desire will make them happy. Whether it is health, money, a loving relationship, material things, accomplishments, a job, or anything at all, the desire for happiness is the bottom line of all of them. But remember that happiness is a state inside of us, and something on the outside can only bring fleeting happiness, because material things are impermanent.

Permanent happiness comes from you choosing to be permanently happy. When you choose happiness, then you attract all the happy things as well. The happy things are the icing on the cake, but the cake is happiness.
