Keyless works fug up's, lume attempts gone terribly and horribly wrong, many, many lost parts = carpet patrol with the wife laughing at how stupid I am, bent hands, bent bezels, scratching the hell out of a case trying to screw/unscrew or pry, broken teeth on gears when a screwdriver slipped.................etc etc etc
I have [censored] up most everything at one time or another !!!!!!!!!!!!!
Many times I have said screw it and wanted to throw all my stuff up for sale or in the trash, but never did.
I just take a deep breath, drink a scotch or two, and try again. Me doing stupid [censored] does not mean the world is coming to an end. It just means I need more practice.
There is no substitution for hands on practice and having the correct tools.
