Dan Egan, the Director of Behavioral Finance and Investments at Betterment, put out a piece about his cash flow management and budgeting. 

I think it is a great piece because firstly, he shares with us his philosophy of why he manages his cash flow this way. 

Secondly, it is because his philosophy, the way he looks at his cash flow, and his budgeting accounts is very different from the traditional setup:

He tries to minimize the cash that he has, because to him, it is a small loss Short to Medium term spending goals are funded by low risk but not no risk assets As much as he can, he will choose to self insure A lot of his spending goals is funded by stock equity portfolio

You should read it, and try to understand his philosophy. 

If a lot of people do what Dan did, there is a high probability
