Optimism is an expectation that good things are going to be plentiful. The wealthy generally have the sense that life will bring good rather than bad outcomes. That doesn't mean they believe that good things will be omnipresent, but that they will outnumber the not-so-good.

Generally, there are three rules when it comes to borrowing money: You need to have good credit, proof of income and cash for a down payment. Most people have the first two, but it's the third that trips them up. And nowhere does that come into play more than the mortgage market.

You could lose hundreds or thousands one day on paper and gain it all back the next, and it has literally no effect on your immediate future, provided the money you have in the market is money you're investing for the long haul (meaning at least three to five years).

What cracks me up is people who think I don't take baseball seriously. It's the most important thing in my life. They don't know how hard it is for me to get a bad game out of my mind. I still can't, but I'm getting better.
