One thing I sometimes find confusing about the mustachian lifestyle is the money vs time issue. It seems that going out your way to save small amounts everywhere you go brings exponential benefits (riding your bike to work for example) but I'm also thinking about the fact that time itself pays you dividends depending on how you use it, and thus you should do things to save time.
I'm wondering whether I should wash my own car or get it valeted.
It takes me 1-2 hours if I'm doing inside and out, vacuuming, cleaning the dashboard, washing outside, cleaning every nook and cranny in each wheel rim, applying polish all over the car, then wax all over. I save £15 doing this. However I can get it valeted and have all of that done in 10 minutes and spend the £15.
I'm not sure whether I should save time or money in this case... and how do I know in the future what things to consider in a similar time vs money situation?
