Make yourself a priority once in a while. It's not selfish. It's necessary.
Happiness is always a by-product. It is probably a matter of temperament, and for anything I know it may be glandular. But it is not something that can be demanded from life, and if you are not happy you had better stop worrying about it and see what treasures you can pluck from your own brand of unhappiness.Robertson Davies
The greatest happiness of life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves.Victor Hugo
There is only one happiness in this life, to love and be loved.
Hard to do, especially when you were raised that it's a sin to think of yourself. But, I agree it's so necessary. Trying to change!
