Well, there is one type of income I was trying to match into those categories but without success.
One of the examples I used in that old post is beggar. I was showing how begging can be E, S and B. However, in real life, no beggar is going to do anything like I suggested there. Beggar simply beg for things without rules, timing or any pre-requisite.
Like wise, I also cann't find a category match for charity. Old folk homes and orphan centers require high coordination and managment skill to make them run smoothly and their 'income' is one of the very important parts.
Sometimes I recycle quite a lot of stuff and I get money out of it. I didn't really spend time and effort to recycle, its more like a mind set and way of life. Yet I get income out of it.
Most religions in our world receive money from their belivers too and form a major part of the religion's income.
All these are real Incomes but not fall under E, S, B and I. So I came up with the 5th category. I don't really have a good name for it yet but I have been calling it "Charity".
Do not underestimate the power of charity. The whole of our society today is run base on this income category.
There are a few ways to identify this income category;
1. It starts with almost 'Nothing' and ends with an 'Income'
2. Since it starts with nothing, you can actually "make any excuses" out of it without penalty
3. It usually touches a human trait to do good, either for himself or for others.
Rob said the best way to earn income is by investing. Well, that is because he didn't know the power of Charity at that time !
Just to bring us back to reality, quite a lot of illegal income falls under this category too.
speaking of which, its about time I need your donation to keep this blog going
