In the U.S. that would probably be around $600,000 after taxes. I would purchase a home for cash in the $250,000 range for cash and invest the rest in conservative money markets. I would use about half of the interest money earned for riskier but more financially rewarding investments.
0% FOR CHARITY - WHY DA FU$K I NEED TO GIVE THEM, IF THEY HAVEN'T PUTTED THEIR A$$ UP TO EARN SOME MONEY BUT JUST WAINING ALL THE TIME? $100K Would go In buying a Car and To Make up pretty big party. and the rest $900k I would spend on establishing Some online project( but not to buy some website) but to run myself it and earn few millions per year.
I would pay off my mortgage, then buy an apartment building, and begin a non-profit organization to house and care for troubled teenagers, and young adults.
