This is true but it's just not realistic. There are situations in life where expectations are totally appropriate. I'd even argue that expectations drive us forward. And if you have no expectation of an outcome, how can you be happy or sad at all at the end? Or how can you tell there has even been an outcome?<p>If I have to drive somewhere and have no expectation of arrival time then I'll neither be happy nor sad when I get there. I'll have just gotten there. However if I severely lower my expectations then I can be happy when I get there.<p>But I'm being pedantic here so I'll bring this back to reality now. Disappointment, heartache, sadness, and gloom are part of life and should not be avoided. We often find the motivation or drive to change and improve through our negative emotions. Sure, it sucks to feel that way but it's just as important as being happy and one shouldn't run from those feelings.<p>If you have good coping skills you can face disappointment head on, feel shitty for a bit, and then plow through and find some happiness or a silver lining. If you've got poor coping skills you'll be running away from all negative emotions and totally stunting your emotional growth because of it.<p>I know the author wasn't trying to write an authortitative piece on happiness so I won't criticize him. What I will do is add a little wrinkle to his whole point which is: Eliminate or lower expectations when the outcomes aren't important. So, for example, traffic is actually a perfect example. If you can eliminate your anger and frustration over being late or being stuck in traffic you're doing yourself a huge favor as being upset over it isn't doing anything for you. However feeling upset and having expectations about your career or a promotion or meeting a pretty girl one day can be quite helpful. The negative feelings associated with not getting any one of those things should push you to change your situation and get them somehow.<p>So all in all, I guess the TL;DR version would be: Apply the article's wisdom wisely, not broadly.
