Anyone else lose interest?

When it comes to building cars, I have the same problem, once in awhile you start to wonder "what hell am I doing.... I put thousands into this car that coulda paid off the house or money i could use"

This is why I don't go too crazy with builds anymore and stick with budget small blocks instead of going full blown hemi and race parts. It's easy to get burned out on anything you get too involved in, including relationships. Although a big part of getting burned out or stuck in a rut comes from stress or depression, it makes anything hard to enjoy.
