Negative behavior is a bad thing to have. You are a lot of time negative or discouraged of something you did wrong or you can't do it. If you mess up on something and then start to become negative about your painting career, don't. If you keep neglecting things it was eventually become and habit and then to the point where you don't even want to try something new anymore because you think you are going to mess up again. It's like running and when you mess up, you stumble, but they think they tripped so they continue stumbling for the negative behavior before they quit. You should never quit, never give up, always get up again. Don't let that little stumble get to you. You are in control so don't give up on what you are doing. If this becomes a habit, you will never ever give up. If you start giving up regularly, you will start to give off a negative vibe. For example, A person sees you throwing down the paint brush in anger and frustration, they will start to get nervous because if you can't do it, they will think they can't do it as well. It will cause the person to start to mess up because that is the main thing on their mind, messing up on their career and what they love. If you see somebody give up, tell them, no, you will not give up. Remember, you are in control, don't give up
