Finally after doing these consistently i can finally play cherub rock without causing a fire on my fingers

That was a very helpful compilation mentioning all the tips I came across in the last few hours in just one video - wow! I am gonna try em all out.

Here's a tip that actually causes pain, but if you can do it, you'll develop calluses FAST : play the opening riff to "When I'm Lonely" by Hootie and the Blowfish until your fingertips are absolutely on FIRE! Then go wash a decent sized load of dishes by hand, or soak in a bath for awhile, and the calluses will fall off. After your hands are completely dry again, pick up your guitar and play, but only for a few minutes. Then start the process all over again the next day, and keep doing that until you eventually reach the point where the calluses stop falling off after they've been in water, and that does eventually happen. But, this is more for first time learners, not people getting back into it after several years, because I'm pretty sure you're only going to have the patience to do this once.

I have a good friend who's a top shelf Jazz bassist who told me the crazy glue trick decades ago.
