Probably a solid 3. I am definitely a jack of many trades, master of none. I often get frustrated at how slow I am. I mean, really slow. But, I can, and sometimes do tackle some very huge challenges that even surprises me. Often, the learning curve is steep. I guess self satisfaction trumps the time vs. money aspect. I also mistakenly think that master tradesmen (plumber, electrician, whatever) would also do a lot of their own work at home with other things like automotive, carpentry, etc.. I am surprised how often these geniuses of their trade claim to leave things like spark plug changes to the experts. Maybe it's just that they have so much money that they can afford to farm out life's other necessities.
Yea, several hours for a front brake job for me vs. 1 hour or less for a pro. A contractor once told me that he could tell that I did the attic insulation in our house........it was WAY too neat.
