I remember someone sometime ago told me that life is all about choices. I feel that life is about living to the fullest. To live to the fullest is to be able to achieve your objectives and at the same time do what you feel like doing the most.
Of course one must live up to their own conscience. Ensure that you feel that you are doing the right thing is important. So that you know you tried your best even if you made a mistake. Make sure that you can answer to yourself. That is the most important thing a person must do.
