Pick a number, and then when that number comes, like a buffalo you find early on a hunt…shoot it. DO NOT allow yourself to hesitate on the trigger thinking, “It’s early there will be more buffalo coming, bigger ones”, only to find that you spend all day realizing that the one you could have gotten you didn’t get because you wanted more.
Happiness comes from meeting expectations. If your expectations are about things you can’t control, you’ll suffer. I do suffer from this at times. If your expectations involve things you can control, you have control over your happiness.
