Aim to have a fulfilled life, and not just a successful life. A fulfilled life is more important than a successful life because fulfilment is judged by you, while success is judged by others. Therefore, you can be successful and still be unfulfilled, which is why many people you think are successful get depressed and sometimes even do the unthinkable.
In life, find out what will make you feel fulfilled and then do it. It does not have to be what people consider as success. If fulfilment comes from travelling or dancing, find a way to work it into your routine. You don't want to get to seventy and be a public success and a private failure. Fulfilling your childhood and lifetime dreams is more important than succeeding the way the public expects you to.
