I don’t have many examples, but to bring one or two up one was my scuba diving course in Thailand.
The dive instructor showed everything and we copied him in a pool. And everytime we had to do all the things I just looked bad.
Another example was climbing. They show how to tie the knot to harness, everyone successfully manages to tie the knot and I am standing their like an idi**.
The thing is what I observed is that if I have time to do things on my own and no pressure I seem to do “okay” and once I can do it I do it blind.
Anyone else experience this? What can I do? I am at a point I am afraid to learn new things because of failing infront of others.
Building on your last point, it could be that others were also already somewhat familiar. Perhaps those learning to scuba dive with OP have experience swimming to the bottom of a pool or have gone snorkeling. It’s unlikely that people would go out of their ways to bring that up to the entire group.
Just remember that people who never fail also do not know what to do in the case of a mishap.
