Be Optimistic, but always be prepared for the worst


there are a lot of ups and downs, perhaps i can ride them out if m prepared for them.
learning to expect problems saved me from a lot of wasted energy, and it will save you from unexpected surprises. its like wall street; it is like life.
the ups and downs are inevitable, so simply try to be prepared for them. 
sometimes i will ask myself why i want to take on some new, big challenge. A substantial loss is always a possibility. Can i handle it if it doesn’t go well? will i be asking myself later, why did i ever do that? what was i thinking? m actually a very cautious person, which is different from being a pessimistic person. i call it positive thinking with a lot of reality checks.
