What can you do?

What do you do when can't do anything?

Let me explain, during the last few yeas I started changing my lifestyle. I became a healthier person with good eating habits, exercising and with a good mindset.

The thing is when you start feeling so good about your change you want others to feel like that too. But you can't change bother unless they really want to.

But what do you do, if you see that someone close is just losing it? If you that the person just don't have enough will power to go against the bad habits? What do you do when you can't do anything?

The worst thing is the need to watch that?
