Don't try too hard because when you try too hard you set yourself up for disappointment. You lose your ability to see things clearly and to stay true to your ideals. In an effort to please somebody, you may end up displeasing yourself. And what's the point of making someone else happy if it results in giving up a part of yourself? Before making your decisions, think how it makes you feel, not how it will make someone else feel. If it seems right to you - go on with it; if it seems like you're doing it for the others - think twice. There is nothing wrong with being a bit selfish when you do it for the right reasons.
