What if you just want to chill and watch TV all day?
I think the last thing people need is more advice on how to reduce fun in their lives and replace it with work, especially under the guise of "becoming successful." If you're 40 years old, have no job and live at home and you're completely happy with that, I would consider you a success.
The worst part about society is the fact that it creates arbitrary tiers where you must reach to be "better" or "more successful" or some other meaningless vapid term. Then it goes further, like this article, and defines "good" stuff you should do that will help you be "successful" or just "happier." I have no plans to follow most of these suggestions for all kinds of reasons... lets see... I hate writing thank-you notes, speaking, volunteering and spending a weekend with people I could be caught up with in an afternoon.
Do what makes you happy. Define your own success. Stop taking canned advice about life from people who know nothing about yours. Make your own damn decisions. I work a ton because I love it, not so I can die with more money or feel better than the next guy. Do whatever makes you feel good and the rest will work itself out.
Edit: Quick clarification. If this were an article about how to be more fit, rested, intelligent, funded and motivated for the sake of those things, then I would totally endorse it. But if you really wanted to be all those things, you'd be doing that stuff already because it's pretty damn obvious. You wouldn't be wasting those 120 minutes on stuff that wasn't making you happy; you'd replace that stuff with other stuff that made you happy. Pretty straight forward.
