First we tackled the daily habits of really successful people. Next we took a look at the opposite side of that coin--the habits of ridiculously unsuccessful people.

Then we asked readers to reach out and let us know what other habits were missing. Sure enough, there are quite a few.

Here are 10 more things that really sad and unsuccessful people simply can't stop spending their days doing.

1. Ignoring.

Here, we're talking about ignoring problems or issues that are uncomfortable to deal with--hiding one's head in the sand. An officer I worked for in the army used to say that bad news is the opposite of wine--it rarely gets better with age. Unfortunately, some really unsuccessful people just can't deal with the stress of modern life, so they ignore problems and hope they'll go away. It rarely works.

2. Envying.

Unsuccessful people are often unhappy as a result of refusing to take responsibility for their lack of effort and achievement. They compensate by trying to pull down the achievements of others. It all stems from their jealousy of those who put in the work, take smart risks, and achieve more success in their lives. It's an exhausting way to live, and it rarely leads to anything good.

3. Resenting.

Envy leads to resentment. Many unsuccessful people nevertheless have to live and work among others who achieve more than they do. Their resentment manifests itself in several ways, but one of the most insidious is by acting passive aggressively. (Know anyone like this? Maybe you understand them a bit better now.)

4. Slow-playing.

Related to passive-aggressiveness, unsuccessful and envious people often play along at being a part of a team working together toward a goal--but the key phrase here is "play along at." Have you ever gotten together with a few friends to help someone move, for example, only to find there's one guy in the group who carries half the load of everyone else, and twice as slowly? (He's probably first in line for pizza and beer afterward, too.) That's slow-playing.

5. Hiding.

This takes slow-playing to extreme, and it's from my personal experience. Years ago, when I worked as an attorney for the U.S. government, we had a colleague who did so little work that it became ridiculous. He literally arranged his desk so that he could hide under it and nap without our boss finding him. Bottom line, people who are never around when there's work to be done are also the least likely to find success and happiness in their lives.

6. Nit-picking.

I'm reminded here of another government bureaucrat I once knew who was the very definition of a "mere manager," as opposed to a great leader. He was obsessed with the petty procedures and processes that were supposed to make our job easier, rather than become ends in themselves. That attitude might have something to do with why I think he's still working at that same job, while most of the rest of us have long since moved on.

7. Condescending.

Condescension is the last, lonely refuge of the insecure--people who have so little confidence in their own knowledge and worth that they try to deflate others by belittling their knowledge. Truly successful and well-adjusted people are happy to share what they know, and to learn from others--rather than hoard their supposed expertise as if knowledge were a zero-sum game.

8. Shaming.

Related again, and rooted in insecurity, wildly unsuccessful people often try to shame others. This allows them to feel like they're part of a dominant group, calling out the arguably negative attributes of others--when in truth they're only flaunting their own lack of confidence.

9. Surfing.

We're taking here about internet-addictions, or television-obsessions--basically anything involving constant consumption of popular culture and meaningless trivia. Granted, we're all a little bit internet addicted these days, but many of the least successful among us spend an inordinate amount of time-consuming media--to the point that it interferes with their lives.

10. Backstabbing.

The last behavior on this list is something to keep in mind the next time you feel betrayed, or when you imagine that someone is actually trying to sabotage your success. Truly unhappy and unsuccessful people are so hurt by the happiness and success they see others enjoy that they can sometimes desperately seek to knock down others' accomplishments. It's an especially evil behavior when they betray trust to do so.
