Why is it everything is so confusing on a computer ?especially for those like me ?

Some people get it and others don't. No two people are completely alike. I understand computers and cars, maybe you understand particle physics and aerodynamics. Or maybe you are a cook in a restaurant and everyone wants you to work for them because you are so good at it. Maybe you are a great parent or grandparent. Whatever you are good at is what you are good at. Don't sweat the small stuff like how you answer stuff. If it is what works for you it's good.
