Komisar warns against the concept of a deferred life plan, when people put off what they really want to do for what is expected of them. According to Komisar, this is when you are deferring your sense of excitement and passion for what you really care about. Working hard is not inconsistent with the deferred life plan, he adds, but doing so for a product that you do not have interest in is.

They say success is getting what you want and happiness is wanting what you get. I don’t know which one applies in this case but I do know I wouldn’t be doing anything else. I’d advise you that when you go out to work, work for an organization of people you admire, because it will turn you on. I always worry about people who say, "I’m going to do this for ten years; I really don’t like it very well. And then I’ll do this…" That’s a lot like saving sex up for your old age. Not a very good idea.
