Also, I would say, even if you think coding is fun or enjoy it, ask yourself if that's what you want to be remembered for, or if you had a year to live would you be happy with having blown it all away on software. I'd bet the answer is likely no. It makes me sad when people in the community pass away and it seems that everyone is just talking about their work, there's so much more to a person (and life) than that.
If I had a year to live, I'd probably go about writing that physics (game) engine idea that keeps nagging me, but has way too low profitability prospects to put months/years into it.
