what would be the perfect business for you?

Its not about what I want to offer , its about what that business would offer ME .A perfect business for me would be one that requires minimum investment of time and assets ,and that pays off quickly and generously so I can have a lot of spare time and concentration to put into studying and getting a higher degree ,and that would guarantee I can leave behind a big lump of money for my children after I die . Do you know where I can find a business like that ??
