Let People in
Its when you don't let other people in that you feel the most alone. In life we are only accepted by others when we learn to accept ourselves. Its very hard, I've been really trying to work on it myself, but it's an important lesson. You should give people a chance, and you can tell when they really care or don't, but if you don't take chances in life and be confident, and try to be comfortable around others, you could miss out on a lot. Just something to ponder.
