You do not need to burn down other homes in order to keep your own home standing on a strong foundation. You do not have to crumble peace in the lives of others in order to use their rubble to build peace in yours.
If there are areas you would like to improve on ask yourself what is holding you back. Are you having dreams or setting goals? Are you making excuses or making plans? Are you competing to be better than others or doing what you can to be better than the person you were yesterday?
