You could feel frustrated a lot of the time without understanding why. It's as if you were a race horse, raring to go, yet you're held back by invisible reins that restrict you to a slow walk instead of a fast run. A lot of energy can get pent up in this process, making you feel impatient and even angry inside.
But something -- your mother's rules, perhaps, or the cultural climate where you live -- has convinced you that it's not okay to express your anger or impatience because it could offend someone else. Consequently you may put the concerns of others before you consider your own needs. They always seem to take a back seat to pleasing other people in your life. In fact, you can be quite impassioned about defending the rights of others, for you have an exquisite sense of fairness and balance and cannot tolerate injustice. You are most forceful when you act on behalf of those who cannot speak up for themselves. These are your finest hours. Expressing your anger is often difficult for you, because you've been taught that it's not proper. Unfortunately this can lead to passive-aggressive behavior until you learn you legitimize your own emotions.
