First, some corrections to make it sound more natural: "Most people are willing to be lazy, or sloth-like, if possible, because it is human nature. In most cases, however, it is not benificial and can even harmful to ourselves. So how do we make it so that we aren't lazy any more? How do you do it?" I'll be the first to admit that I like to stay home, be lazy, eat a pizza and watch a TV series or movie. However, I also like to go out too. I think the trick to overcoming laziness is to plan activities, especially new ones I haven't done before, ahead of time

I don't know. Sometimes when I get lazy, I go to the gym. Working out helps you let off steam and it keeps you busy. By the way, your initial post needs fixing. Do you want us to do it? ;)
