I guess it just depends on what gives you the greatest satisfaction,,, Is it the journey or the result?
Having spent a (working) lifetime doing "stuff" that other folk wanted now, as a retired old git, I please myself. I have a lot of projects and I progress each as I feel inclined – they are all my choice and the only one concerned about completion dates is me… ( and I'm not very concerned!) It's a hobby that takes up as much or as little time as I want. ( I do get the occasional "rush job" though – usually of a "domestic" nature – and these are, naturally, given top priority as any other course could adversely affect my Health, Safety …and Comfort position!)
