I consider it a bad habit if you leave a rest of food or drink everytime you eat or drink.
I also consider a light gaming addiction to have a more negative impact on your life than any other light addiction (well don’t get me wrong, I’m not talking about illegal stuff here!)
The Parkinsons Law (also revisit the “Student Syndrome”) says: You can do things quicker than you think, you mostly take a long time because you just give yourself too much time and fill the “spare time” in between with useless stuff (like writing blog articles or being on twitter). Nike translates: “Just do it“. After all, you get cought by Hofstadter’s Law after that: “It always takes longer than you expect, even when you take into account Hofstadter’s Law.”
I think if you really want something, it might be worth changing yourself to get that. In fact, many people don’t want to change. The only way not to want that is to assume you’re already perfect – or out of laziness. So, is everyone lazy?
Smoking is a bad habit too. Nobody wastes more money on earth to destroy their life than smokers.
If you get followed by someone with a lot of followers on Twitter, don’t be flattered. They use scripts that follow everyone they can get and will unfollow you if you don’t follow back. In my opinion, you should follow those who have something interesting to say, not those with a big follower count.
