Not quite as impressive, but if you look at my January 2014 net worth (approx. -$36k), to January 2015 (approx. +$8k) I don't think I did *too* badly last year. I made about $70k.
Even bigger better plans for this year - I'm buying a house much closer to work, which will hopefully allow me to sell my car and start biking to work again. The car sale alone will eliminate all of my remaining debt (well, except for the mortgage), and shift my net worth needle by about 20k, and that's before even factoring in things like insurance, gas, fitness benefits of biking, etc. The house itself also isn't any more expensive than the place that I've been renting, but as I'll now have extra bedrooms and live in a touristy area, I also plan on starting an airbnb side hustle. Should be interesting :)
