You did everything right: maxed out your retirement accounts, invested in index funds, paid off all debt, saved half your gross income, and did every home project and car repair yourself to save money. If you are like me this describes you to a T. I save a massive amount of my income in tax advantaged retirement plans and stuff non-qualified accounts, too. Very few jobs are off-limits to me. The roof is bad; I go up there and spank on another set of shingles after tearing off the old ones. A bad light switch is an easy fix after a short visit to the hardware store. I clip my own lawn at home and the office; I grow most of the food I consume; I bike to work even though it is a 30 miles round-trip; change the oil in the car; and I have no problem with a paint brush.
The DIY movement is alive and well. Taking the bull by the horns and getting a job done can save massive amounts of money. Early retirees get to their exalted status because they kept costs low. Frugal people are drawn to DIY projects like flies to honey. With so many people undertaking projects on their own it is time to ask an obvious question: Should you be doing that project on your own.
I have seen some really bad DIY jobs over the years. Buying a large number of rental properties over the years revealed some doozies. Still, I handle a large percentage of jobs around the office, home and farm on my own. There are times I do need to take a knee and bring in somebody with experience.
