I'm somebody told me that I could make $50 for saying hello to someone on their birthday and it would only take me 2 minutes, I would schedule a half-hour a day and do as many as I could in 30 minutes. That's around $2,500/week for 2.5 hours worth of work ($10,000/month) if you do 10 a day, M-F. Again, that's only $120K/year. For me now of course I'd love to have that extra income for a little of my time. But if I have millions in the bank and still actively work that's not going to be enough to move the needle.
