To your creator, to your benefactors, to the people around you that affects you in any positive way everyday, being grateful is the only real way that you can repay most of these things, I do not only agree with your post, but also share of a further view that gratefulness is one of the solid foundation of a winner's life. It remains that as a man cannot succeed in isolation and no successful institution can be one being an island on its ow, it is thus paramount that people respond to the kind of treatment they get and a show of gratitude always go a long way in getting them to always be on your side. Gratefulness is a broad topic and one that could take a book or more to exhaust, but the bottom line like you pointed out in your work remains; He that is grateful stands to get more.
