Don't feel bad, super glue hates everyone, equally. I find the only way to deal with it is to put a tiny dab on a piece of wax paper (or waxed cardboard) and then use a pin (or similar tool) to move an even tinier amount, to the surface where you're attaching something. Any other way leads to nothing but disaster. I've tried those fancy tips and after a few uses, they're all gummed up and worthless.
As for your vision dilemna, you might want to look into something like an Opti-visor (or even one of the knock-offs). They'll work in conjunction with your glasses, or in place of your glasses if all you're looking for is magnification.
What's your main area of interest - planes, armor, ships, autos? I'm a plane guy, but when I got tired of doing, essentially, the same thing over and over, I built a tank. Really re-sparked my interest in building. So much so, in fact, I picked up another 3 armor kits (and another plane ). You might want to try building something that isn't your main focus - you might be surprised how much it helps.
