I started programming with a friend, I remember our first Js and PHP, he got stuck often, stopped for months while I was getting some first contracts, he was in awe about it and I thought he is hopeless, he always kept saying we will make it. He continued to go to local meetings where most people used phyton,c ,anything but what we used. Then I moved away, couple years later, he informed me he is some sort of full stack engineer at IBM, still is. That was a big lesson to never judge one based on early results. This guy didn't understand function arguments and how return works for a long time. I was bad at geometry initially as well, but with the help and encouragement of teachers, i managed to improve beyond class average. Some other topics, there was no help nor will and I stayed well below average. Motivation and dedication and external factors like help can neutralize intelligence adv/disavantages at times, seen it happening over and over.
