Honestly for me it isn't even taking on the big jobs that bothers me, it's the jobs left unfinished. I've always been eager to jump into just about anything but in the last several years I have unfinished jobs piling up all around me and it drives me mad.
A few years ago I started a restoration for my dad (his truck) then because of him retiring and my brother getting a divorce they started occupying the garage making it impossible for me to work so I started building my own garage and eventually moved the truck project into it. Before I could finish either we decided to install an outdoor boiler, then with a growing family we finish the basement adding a bedroom, laundry room, bathroom and a rec room pushing the garage even farther to the side. Wasn't long before the wife wanted hardwood in the living room (carpet was getting old) which snowballed into a radiant heat floor which led to raising doors, stairs, etc and it just keeps going. We recently added another little guy to the mix so talks of adding on yet again with an attached garage with living space above has begun..
It's all good, I'm extremely blessed just need to finish a bunch of stuff before biting off even more.
And one more thing, the daughter just turned 15 and we haven't even touched her 72 Satty.. tic toc, time is running out!
