Nobody can take your education or your ideas away from you. They are yours forever. The only way to know if something is true is to challenge it and see if it still works. Also don't be afraid to feel, because emotion acts as a great motivator. It is important to feel the depths of human emotion, ranging from that gnawing, empty pain to the ecstasy of joy.
Many people choose to feel nothing, and become numb because it is easier to feel numb.
Don't do it. Try to feel all the experiences of others, as well as your own, because the only way to truly understand anything is reached through your heart, not your mind. If everybody were perfect and content, nobody would care about each other because there would be no reason for it. Just try to also understand that there are injustices in the world, but you don't have to subscribe yourself to them. Even if you feel as if you are fighting a losing battle, fight anyway, because this gives you integrity.
