However, you may still be sad that you cannot do everything you might like to do. It is an essential truth about life that every time you make a decision, you also experience a loss of some alternative. I will probably not be able to be an astronaut in this life, and with my interest in space, that’s a little sad. But it does not mean I should have chosen it as a career. When you buy a chocolate ice cream cone, it means you are not eating strawberry. But you accept the loss in order to enjoy the chocolate. You owe it to yourself to focus on the ice cream you have chosen.
