I'm trying to improve myself because of my dog.
Is there something you want to achieve by improving yourself?
I want to be a better human being.
Most people don't take the time to better themselves, unless they have to. I think it is a very worthy, noble goal to want to be a better person.
I agree and I hope to increase my self-worth.
Working on yourself has many benefits and I think your goal to be a better person is a great one. It's wonderful that your dog has motivated you to take such a positive step in your life.
