I always want to start my own business. Buy an office, and hire people to help me with the new business.
Invest $50.000 in my favorite niche site to create and be the best out there in that specific niche. I'll write and do something that I love. The rest of the money I'll deposit in banks. Will also start traveling a lot, like leaving 1 month in a different country for a couple of years till I'll find the best one...
