Did you pay your taxes already ? I wonder what 
    would be your after-tax income ? Again, $2.5k 
    is still very low even for Eastern Europe.

I don't know which Eastern Europe you live in - but $2,500 per month (even if he ends up paying 50% taxes on it) is considerably higher than average income in Poland, the Czech Republic, Slovakia or Hungary.

And if we are talking about non-EU member like Ukraine, Russia, Belarus or Moldova $2,500/month puts you firmly into the ranks of the higher class (except maybe in Moscow).

It is my total income. I need to pay taxes from it. But when I get full time job I need to pay similar taxes so it is still over 2x more that I would make on day job.

http://en.wikipedia.org/wiki/List_of_countries_by_per_capita... speaks a different language even if you factor in taxes.

I am always a fan of a safety net but in the case of kreci the upside of continuing his path surely beats dedicating his resources to a full-time day job.

It is not low. My salary as expert in financial institution is waaay below this.

After-tax would be around $2k (the effective tax rate for the self employed is 19%). You can live very comfortably on this in Poland.

Or even in western Europe. My regular household expenses, mortgage, etc, are around $2k and I live in the UK, have a kid, a mortgage, a gas-guzzling car, give my wife housekeeping each week (she doesn't work), and we are more than comfortable. I could even make some big cuts into that.
