I agree, but I think you lose that patience for reinvention in about year 6, not year 21. So, dealing with it becomes part of being a software developer. If you can't, you won't get to year 7.

And yes, there are more responsibilities with age, which means you also have to improve your time management. But, that's not unique to software developers. Waiting to see how new technology evolves before jumping on the band wagon is a good time management strategy for software developers.
