After a comment the other day with someone who is quite like me, I realised I love to be building something. The comment she made was 'I like to be building something'.  Ok so I totally copied the phrase (just gave it a bit more oomph) but basically I knew from my teens that I didn't like routine or repetitive work (thanks, Careers test) although I think now, I DO like it if it helps me develop or learn a skill or skills I didn't have before. But once I have mastered the skill (and my version of 'mastered' isn't as much as 'mastery') that's it, I'm done.
