I agree with this, probably because it fits my situation so well. I work a mind numbing pharmacist job, save 85% of my income and am working in side projects. One project is medical software because everything out there is currently very shitty. The savings are invested cash flowing securities. In five years you will have built up decent cash reserves.

Now, you won't necessarily be living like a pauper. Just stop buying stupid shit and buy bare necessities.
