Stay True to Yourself
This is short and sweet but profound.
Don't worry about what people think of you or about the way they try to make you feel.
If people want to see you as a good person, they will. If they're going to see you as a bad person, absolutely nothing you do will stop them.
Keep your head up high, and be confident in what you do.
Be confident in your intentions and keep your eyes ahead instead of wasting your time on those who want to drag your back.
Because you can't change people's views, you have to believe that true change for yourself comes from within you, not from anyone else.
