I think this make a lot of sense, good tips from Warren Buffet.
On earning: Never depend on a single income.
On spending: if you buy things you do not need, soon you will have to sell things you need
On savings: Do not save what is left after spending, but spend what is left after saving
On taking Risk: Never test the depth of river with both feet
On investment: Do not put all eggs into one basket
On expectation: Honesty is very expensive gift, Do not expect it from cheap people.
