You want a very simple way of leading both a better life, a more ethical life, a deeper life, and a happier life? Before you do anything, ask yourself the question, "Will this make me happier?" If you took this advice for a week, it would change your life. Just ask before you do anything. Before you go to work, "Will going to work make me a happier person?" Not, "Will it be fun?" not do I want to get out of bed, will I be happier because I went to work? Would I be happier if I did anything or don't do anything? Will I be happier if I watch TV for 4 hours today? That really makes the case that you should pursue happiness. That's the most obvious, most direct way of pursuing happiness. Will this make me happy? That's what you should ask. And the answer should be, wherever possible, a guidepost. Even if you don't like your work, you will be happier that you went to work because the alternative is not to have an income. Remember, I didn't say, do you like it? I didn't say, is it fun? I'm just asking you, will you be happier for having done it?
