Im enthralled that you posted Mr Honnolds video. Honnolds presentation mentions rigorous preparation, repetition and rehearsal of every move, citing that the challenge for him was mostly mental and psychological.
Unfortunately we as arborists don’t necessarily get to practice the exact tree we have to remove ad infinitum. With that said, I also think it’s unfair to use Honnolds as an example.
Check out this fMRI scan showing Alex’s reaction to stimuli (that would bother other people). Alex’s brain - whether by original design or extensive training - clearly doesn’t expérience stress, risk, or fear the same way that the rest of us do

To OP, you mention these trees were around 100’ tall. Chances are, if you développéd as a climbing arborist where
@rico works, you would start to get equally freaked out at 200’, but feel cozy at 100’
Take some time on the weekend and go rec climb some 80’ trees. As others have said, bounce around, take some swings. Once you’re comfortable in that, go find 90’ tree, repeat. With exposure you will get more comfortable
