Welcome to the community. I am 73 and sometimes wondered the same thing, though after 2 years, I’ve proven to myself that I can do it. I’ve had some experience with supplements, Galantamine, B-6, Gaba, Chaga and others, and with different techniques. I have had recent good luck with the techniques cited in this research.
We have a dream group meeting on Sundays and I derive a lot of motivation from those Dreamanauts each week. They’re characters in my day-dreaming. A couple of weeks ago Emeric’s tale of trying to fly into space inspired me enough to do that that very night. I like Steve’s advice above and he’s helped to inspire me as well.
