When you get paid enough to live a comfortable life in a spacious, one bedroom apartment in a low crime neighborhood, are able to qualify for a mortgage but you won't cuck yourself for the bank, are able to enjoy expensive, high quality copes, and are able to save enough money in a fair amount of time to make big purchases or investments without needing a loan.
And it would be best if you did this as a self-employed contractor, who can do a job for a few months, then have enough money to LDAR for the other nine, should you choose.
