Putting it into practice is the hard part!
I got the same itch a few years ago and imposed a ban on new projects "unless it was a screaming deal that could be realized in less than a week"!
That little phrase is killing me!
As for too many cars...I am over the top. Just picked up car 74 and 75 last week, a 2003 and 2001 police Crown Vic that needed a day of diagnosis ans $70 in parts to be dependable cars...Screaming deal? Well, the gubament collected another 80% of the purchase price in license ,title and taxes.
How do I pass up on a $250 Escort wagon with a bad engine knowing I have 2 good engines sitting in the shop!
Or the $500 miata (worlds ugliest candidate) with a hardtop!
On the flip side is fear of not having the parts needed. Hauled the nieces Honda to the scrapyard finally. Literally the next day a nephew (I think!!??) needed an alternator and exhaust manifold for his Honda. He could have used a window motor, spare tire, front valance, headlights and some dash pieces too!!
Start trimming the excess away, but never look back.
