I can certainly identify with Eristheunorganized - I didn't wear makeup until age 25 when people started asking me almost every day if I was sick, sad, and/or overtired. I got sick of that so I started wearing makeup to work only (and the rare fancy night out). Literally takes 2 minutes to apply in the morning (mineral concealer & foundation, light mascara & blush). Costs about $75/year. And honestly I surprise myself more than once by my own reflection - it really does look much nicer in the mirror with the makeup than without, though I prefer the natural look any day. ("Looking nice" doesn't equal "truly happy and content" for me, but I understand for some people it does).
Uh oh, now I'll have to decide whether or not to wear makeup to my first MMM meetup... ha!
