  My friend has the same job and same hobbies. I think completing tasks you can't physically see an immediate reward for doesn't hit the same reward centres as the things you describe. Also the work is never done at work, where as physical things have a process to completion with an environment improvement as the goal?
context: Not exactly the same, but I work as a housekeeper and gardener. I excelled in school and have a law degree, but physical work soothes my soul in a way that law and similar occupations never would. >
  
  I have worked in I.T for more years than I care to mention. Stick me in the garden to get on with jobs or decorating a room, build a BBQ. I much prefer this it's relaxing and very fulfilling.
