Change yourself

Don't waste your precious time trying to change anyone. Instead change your attitude towards them. If you have no choice but to be around someone in your life that you think makes your life difficult, trying to change them is a moot concept. People can only change themselves. So change your attitude towards them. See them in a more positive light. Because truth be told difficult people will always be around. Changing one of them doesn't fix the problem. However, changing yourself does.
