set aside what i need for taxes....(let's just say $200k)
leaves me $250k, I probably put $50k in the bank/investment accounts. Use another $50k for fun....i.e. car, trip to vegas, toys, parties, buy some crazy stuff for parents.
$150k into a business. The biggest thing stopping people from going into business is the capital. If i lose it then that sucks but at least it wouldn't affect my house, credit, etc.
