Honest question: why do you think gratitude is a trick for success? I can understand for happiness, but don't you think gratitude is often at conflict with the inner drive needed for success?

No, I'd argue they're orthogonal. A purely self made man or woman is a rarity these days. Showing gratitude is a low cost way to strengthen your support network.
