[Marvel] Since Thanos is super smart, does he realize he is a huge klutz?

Thanos is as smart if not smarter than Reed Richards. Does he realize 99% of the time his schemes fail, he is the main reason for the failure? He seems pretty clumsy, and I'd assume, Thanos being Thanos, he should have addressed this issue at least once.

I feel it's important to point out its not nearly a 99% thing. Its happened twice - he list the Infinity Gauntlet because he became arragant, and when he had the Heart of the Universe and destroyed the universe - although here he does vemkanw that he was just acting as a pawn for greater powers (TOAA). 

Other than those instances hes been killed by Drax in Annihilation, which he couldn't predict, he's been turned into stone by Adam Warlock after fighting all the Avengers (and winning for the most part), and most recently he was imprisoned so to speak by his son, whilst fighting and beating the Avengers yet again *and* being betrayed by one if his Black Order.

He does admit that he is the reason for his downfalls often though, but he can't change his nature.
