"My basic principle is that you don't make decisions because they are easy; you don't make them because they are cheap; you don't make them because they're popular; you make them because they're right." by Theodore Hesburgh

This quote means that you have to make the right decisions because the wrong ones will lead to bad things. It is also saying that you don't make a easy decision because every decision leads to a big part of your life. Also that decisions don't cost anything, so you should always choose the right. Therefore when other people make bad choices, doesn't mean you have to as well. So in this case you should surround yourself with positive good people.
