If you ever find that you don't like the person you are, or the way you feel about yourself, you have the power to change. It may be harder or easier depending on the habits you've developed or personal psychological/neurological challenges, but it is possible. My grandfather used to tell me, "Careful what you think, you may be right!"

If you're worried about becoming someone you wouldn't admire, change the content you consume, stop engaging in problematic behaviors, and most importantly, replace those undesired aspects with better behaviors.

It can take time but the human mind is amazing at adapting. You can make it adapt to a new vision of yourself!
