It’s in our interest to take care of others. Self-centrednes s is opposed to basic human nature. In our own interest as human beings we need to pay attention to our inner values. Sometimes people think compassion is only of help to others, while we get no benefit. This is a mistake. When you concern yourself with others, you naturally develop a sense of self-confidence . To help others takes courage and inner strength.
As far as your personal requirements are concerned, the ideal is to

Whether you believe in God or not does not matter much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life.
Reincarnation is not an exclusively Hindu or Buddhist concept, but it is part of the history of human origin. It is proof of the mindstream's capacity to retain knowledge of physical and mental activities. It is related to the theory of interdependent origination and to the law of cause and effect.
