It's true that sometimes we find something fulfilling late in life. But we should also factor that our mind (and thus perspective) biologically change as we age. So what you find fulfilling now at 50 may not be something you may have enjoyed in your 20's or 30's. I remember as a teenager I used to consider kids below 10 dumb pain-in-the-asses. Today, as an adult, I mostly enjoy interacting with them and find their perspective and curiosity really interesting.
