But none of that really matters. Don't plan for the next three years. Life is long, plan for that.
Many of the people I worked with in the '90s achieved a sort of fame like the fame the people you see achieve today. But when their achievements were superceded, they didn't go and do new amazing things. Instead they didn't do much at all, or did things that were completely tangential to their skill set, things they couldn't really excel at.
Part of the reason was that, having worked their way to huge XP, they couldn't start at 0 when they needed to restart the game. So they just didn't play. But we all start back at 0 when we do something new. We progress faster the second and further times around. We talk about learning from failure and doing better the second time around. These people couldn't learn from success.
So now I admire most the people who can achieve thing after thing, even if each of those things is not fame-worthy, not so much the people who have done a single thing, even if that thing gets a TechCrunch headline. The turtle, not the hare. I think the turtles do more good over their lifetimes than the hares, and that people who continue to be productive year in and year out are much, much happier.
My fears now are a different sort: do I still have time to accomplish the things I want to accomplish? Then I remind myself that I still have another 30 or 40 years of work left, as much in front of me as behind me. I encourage you to think that way: you have another 60 years of work left...what can you do over the course of 60 years? Pick a long-term goal (interstellar flight, artificial intelligence, peace on earth, whatever), break it into manageable projects, then start.
