I helped Bob tile our bathroom, it took longer that I remember it taking to tile.  Next tile job, I may hire someone.  The repetitive bending, stooping, twisting, spreading thin-set, placing tile over my head, etc. Lead to a pulled muscle in my back.  I’ve been in pain for almost two weeks.  This past weekend I spent flat on my back, on muscle relaxers.  I do not like laying around when I have so much to do! 
Hmmm, two weekends ago when I was painting the basement I may have said, “I hate having so much more to do…wish I could just lay around all weekend.”
Grass greener?  Or, be careful what you ask for?
Maybe just-learn to be content in any circumstance.  Busy or flat on your back.
