Like it or not, work is one of the few things that gives life meaning. You cannot possibly expect your life to have much meaning unless you are doing something that you love and care about. And if you are doing something that you love and care about, how can you aspire to just be good? If all you want is to be good enough, then you are not doing the work that you need to do.
You need to be doing something that you have the possibility of becoming great at. And if your work is simply not a possibility, then you need to become involved with something that you are passionate about. Something that you can help to make great.
So why are you going to spend your working years – the best years of your life – doing something that you do not love?
