I want to develop good habits

Hi. Nice job! I rewrote it to make it sound more natural. Many of the things I changed weren't really wrong, they just sounded a bit awkward. There are some parts that are a little vague, and it would be easier to understand your meaning if you included more information. Good job and keep studying!

I have many bad habits, like staying up too late at night and playing games on my cell phone and computer. It sucks because it wastes a lot of time that I could be using to better myself. Today I thought of something strange and almost did it, but finally I came to my sense and quit. (This sentence is a little vague, it would be better if you could describe what that thing was) This meant a lot to me because it was the first time that I tried to beat the evil in my mind and won. I'm starting to believe that I can be a better person in the future if I can stick to it.
