To Improve my Bad Habits

I have bad habits what that I would like to improve/fix, but it would take quite some time (to fix them).
Although I feel a little bit embarassed  to talk about my bad habits though, I decided to write one of them.
It is that I want to give up to spend wasting time stop wasting my time. For instance, I want to stop watching TV, to surfing the internet, and to going window shopping without objectives. Not to watch TV and not to go window shopping are almost done with improving. I am almost there with refraining from watching TV and window shopping. 
But the most difficult thing is not to surf the internet. The reason why is, at first I look up something I don't know through on the internet, and then I find something new I don't understand and keep looking it up, and then I am repeating repeating the same cycle. In the meantime After a while, I realize I have spent some time while forgetting my first objective.
But I believe that bad habits would get improving be improved more easily with practice like learning languages/language-learning.
