Quite an aspected mars there, strongly flanked by the sun/pluto squares, though in accidental fall being in the 7th. Opposes the ascendant and hence conjunct descendant - do you find yourself attracted to martial types, i.e. courage/toughness being a trait you deeply admire in others?
I can't help but think the mars square pluto would never feel like it's doing enough, irrespective of however many challenges it has mastered - I can imagine it feeling that there are always more walls to break down. And the semisquare to neptune implies doubt of one's own capacities in this area. Add to that the square to the MC and I wonder if you are particularly concerned with others perceiving you in this manner. The MC bit is entirely you feeling like you needed to prove it, imo.
I get the impression it would be a highly dynamic and inventive sort of mars given all of its influences, namely being in aquarius sextile that uranus. Hell I'd swap you mine
