| One of the more common and destructive mental tendencies I've seen is that of focusing on what we want instead of what we have. We want this or that. If we don't get what we want, we keep thinking about all that we don't have and we remain dissatisfied. If we do get what we want, we simply recreate the same thinking in our new circumstances. So, despite getting what we want, we still remain unhappy. Happiness can't be found when we are yearning (向往,渴望) for new desires. Luckily, there is a way to be happy. It involves changing the emphasis of our thinking from what we want to what we have. Rather than wishing you were able to take a vacation to Hawaii, think of how much fun you have had close to home. The list of possibilities is endless! Each time you notice yourself falling into the "I wish life were different" trap, back off and start over. Take a breath and remember all that you have to be grateful. When you focus not on what you want, but on what you have, you end up getting more of what you want anyway. If you focus on the good qualities of your spouse (配偶), she'll be more loving. If you are grateful for your job rather than complaining about it, you'll do a better job, be more productive, and probably end up getting a raise anyway. If you focus on ways to enjoy yourself around home rather than waiting to enjoy yourself in Hawaii, you'll end up having more fun. If you ever do get to Hawaii, you'll be in the habit of enjoying yourself. And, if by some chance you don't, you have a great life anyway. Make a note of yourself to start thinking more about what you have than what you want. If you do, your life will start appearing much better than before. For perhaps the first time in your life, you'll know what it means to feel satisfied. |
