Will start as soon as it gets cold again
Or maybe take a ski trip if you can! And extend the season. I started to ski a few years ago, and i was no youngster. I used to ski like shit, and I am happy to report that I still do. The good news is, I don't give a shit, so it all makes sense in a holistic way
But yes, like most people mentioned so far, and I can relate to that, you can learn. Enough to move around, all over the mountain. I do think the things that help are lessons, equipment ... and time on snow! So, ski as much as you can, and have fun.
I was reading your OP and boy, do I sympathize. Season one was just about not falling too often, on "greens". It was ridden with fear. Season 2 I had this intense fear of getting on the wrong run. Three seasons later I was skiing some of the expert terrain, off-piste. Like shit, yes, but safely. I didn't look pretty. But I am not dying to "look pretty", or impress anybody. Or prove anything. I just find that a combination of good equipment, instruction, and time on snow allows me to go to more places in the mountain, in more challenging conditions. These days i rarely ski on a "run", I mostly go to whatever place doesn't seem crowded, and it's all natural beauty. This is your reward:
So, I am glad that you got plenty of encouragement and good direction in this thread, and you seem to be on the right track. SkiTalk is a great place to get good advice. Once you get to about 30-50 ski days, with proper instruction, the fear will be gone, and it will all be pure joy. We have the privilege of being kids again, on a gigantic, natural, amusement park. Enjoy every moment of that, and don't let anyone rain on your parade. You will be good enough to have plenty of fun, and there is nothing else that matters. Nothing.
