The Mega List Of 145 Bad Habits To Avoid

It’s much easier to pick up bad habits than to build good ones.

Everyone has habits they know they should break for one reason or another. 

But how do you know when something actually is a bad habit — and not just a quirk? 


Quirks are cute. Bad habits . . . not so cute.

When was the last time you felt warm and fuzzy after someone launched into a political rant at the dinner table?

Bad habits can have long-term consequences for you and the people you care about. 

Hence this list of 145 bad habits to avoid.

Because once you call those habits what they are, you can take action to replace them with better ones. 

What is Considered a Bad Habit? 

A bad habit would flunk a cost-benefit analysis. When you’re honest about why you haven’t broken the habit and about how it affects you, the cost is greater than the benefit. 

And you want to quit it. You really do. But it’s still hard. Because it’s a habit. You do it without thinking. And sometimes, it makes your life a tiny bit more tolerable in the moment. 

After all, some folks call an awful lot of habits “bad” that don’t really bother you.

So, how do you know it’s truly a bad habit and not just quirky behavior? Look for the following clues:

  • It can adversely affect your physical, mental, or emotional health — or someone else’s.
  • People you care about find it annoying or repulsive, and they wish you’d stop.
  • It breaks customs, laws, or social mores.
  • It can be stopped with an act of the will and with consistency (unlike a mental or emotional health challenge).
  • It could stop you from becoming the person you want to be.

Some bad habits are worse than others. And you might have some habits that would appall someone proud of their good habits but that don’t really bother you and the people whose opinions of you matter most. 

Don’t choose which habits to break based on what Miss Manners would say. This is your life. And you’re the one most deeply affected by the habits you keep.

Ask yourself, as you find your own habits in the list whether you want to see yourself with those same habits five years from now.

If you have any of the following habits, you’re in good company. These are the most frequently mentioned bad habits, and some of them you may not even want to break. Or maybe you just don’t consider breaking those habits a high priority.
