“When I do good, I feel good. When I do bad I feel bad.”

Abraham Lincoln

This quote means that when you do good you will feel good. It gives you peace when you know that you have done good. When you do something wrong it is on your conscious that you have done something bad. For example, if you help an elder cross the street or help them by carrying their groceries to their car, you will feel good about what you did and know that you did something good. On the other hand, if you steal from someone, you will feel bad that you did something wrong. It will be on your conscious and you won’t be able to get that feeling out because you know that you have done something wrong.
