You could say that Nam didn't find the bounty hunter profession, rather it found him. Nam's self-awareness has always been his biggest weakness, which was put on full display when he attempted to break the ice on Nal Hutta with a local hutt crime boss names Derna.

While his attempt was well meaning, his enactments of hutt mating mechanics and near constant phrasing of "that's what she said" resulted in the hutt sending several bounty hunters to forcibly remove several organs, which were extensively listed in the bounty marker.

Though he can be thoroughly grating on nerves, many are quick to forget that Nam was born and raised on Mandalore. The bounty hunters sent to extract organs were reminded of this the hard way. Though sometimes seeming aloof, when put under stress Nam's childhood training in combat and piloting triggers. This matched with his love of tinkering with gadgets and hobby of understanding underworld lore makes for an effective, if unconventional bounty hunter.

When credits started to run low, the mysterious Doma Drand reached out with the offer of work which Nam immediately accepted. Because strangers are just friends you haven't met, he told himself.

Nam'sub is perpetually broke, spending his credits before they even have a chance to get warm in his hand. This causes him to take on all sorts of jobs and take favors as he lives in the moment. This is partly his personality, but Mandalorian bounty hunters are not exactly known for retirement.

10 Favor: Always short on money due to poor investment choices, Nam found himself in a tight spot on a backwater outpost with no credits for fuel. He had credits when he landed, but spent them all on a new food discovery, the blooming ration with a porg ranch dipping sauce. He had to call in a big favor to the Blacksun underworld organization to get extracted. They seemed very nice and only asked for a favor in the future. Seems like a good deal...

10 Blackmail: A back world mission didn't go as planned. The new whistling bird mini rocket launcher Nam was using did take out the target, but unfortunately 9 others on the street, including some royalty who were on a diplomatic mission.

Fortunately the holovid security footage was removed before the authorities could determine who was involved. Unfortunately that footage is current in the hands of a minor Hutt named Grell Zorda who reminds from time to time that it would make life difficult if the footage were to get out. Nam think's he's just teasing him, but if it got out several royal families would likely take large bounties for revenge.
