I’m 6’5” too.
People have an expectation of competence from tall people, which can be tapped into, assuming you carry yourself with confidence, and you can reasonably meet the expectation.
My dad taught me that, so here is my life timeline
Played high school sports.
Volunteered for the military. Trained and deployed in spec ops. Survived.
Became a Krav Maga instructor, plus contracted for security work for US personnel.
Put myself through college and grad school.
All of these things, or any one of them, gave me confidence. I can’t read minds, but I get the impression that people sense the confidence, so they trust and hire me.
Size and confidence are a great asset.
Size alone is just a growth phenomenon.
