I have to chuckle reading these type of posts.
Amount of money has nothing to do with it. its all about allocation, diversification, and percentages.
Many of these guys deal with friends or referrals from friends. Well meaning, but not good at what they do. put them in poor allocations, high risk (can you spell restaurant or bar?). Or the spend too much from the get go. There are also many athletes who are smart with their money and have lived within their means and will do fine the rest of their lives...( the dumb hillbilly in Mississippi?)
I do this for a profession. People of all income levels live within their means, live above their means, invest wisely, or poorly, listen to an expert (me) or a well meaning but poor advisor (brother in law, son, daughter, parent).
reality is your investments should match your goals. You need to know the risks associated with each investment and have an overall strategy...then make sure your individual investments meet that criteria.
As far as taking care of your own money, at the level they are, it is like a small corporation. too big and too many transactions for one person. Where they fail is they do not have proper checks and balances implemented. They usually haved a buddy take care of their financial stucc (car payment, CC payment, house(s) expendetures, etc. These guys arent professionals just trusted friends....
