Add in skills and traits that everyone has. Nobody can fault you for it because they don't know.
"Perfectionist" is a good one, if a tired cliche. Also consider "Maintains a positive attitude" "Legally Qualified Martial Arts Instructor" "Capable of doing tasks" "Can make Toast and Popcorn" "Good Hand-Eye Coordination" "Fully functioning inner-ear fluids" "Good vision" "Can play an instrument" "Can sharpen a pencil with just about anything" "Authorised to hunt bounties in most states" and "Willing to Learn".
In past jobs, add in really, stupidly vague fields that sound prestigious but can apply to anything.
"Salesman" "Appraiser": When asked to clarify, say you've earned hundreds of dollars on Ebay and Craigslist and your friends come to you to judge the worth of their scrap electronics and old video games and shit. They will never attempt to verify this.
"Antiques Collector": Anyone who owns a furniture shop is an old fuck. That's just common knowledge. If you have any game cartridges or systems from the 1990s or prior, just tell them you collect vintage software and talk it up, making everything sound like a much bigger deal than it actually is. They're old fucks, so they will have no way of knowing what you're talking about or whether it is really as grand a game of trade as you say it is. (It isn't, really. Your average Atari cart will sell for maybe ~70 cents a unit, unless it was hella popular or they only made 200 of them before going bankrupt.)
"World Traveller": Have you been to another state? Good. Embellish, you're Ford ffs.
"Cinema Critic": Rant about anime online and convince one of your friends to give you money for it. Congratulations, you are now officially a paid critic and your future employer will naturally assume that you're much more impressive than you actually are, because critics have a natural air of superiority on account of being critics, and nobody except people who try to write for money know how difficult and shitty it is to write for money. Everyone who writes must be famous on some level, that is fact to the plebes.
"Handyman": Say that there's nothing you can't do with time and duct tape. Make a 3D graph where the amount of things you can fix exponentially increases with the amount of duct tape you have and the amount of time you're given, with a slight bias toward duct tape so it looks like you're really skilled with duct tape rather than just using a long time to apply hoards of duct tape and/or come up with something decent. Make lots of points and numbers. Your employer will be so bedazzled by the graph and his overall not-give-a-fuckness with who he hires for his minimum wage furniture store job that he'll just hire you because you were smart enough to make a fucking XYZ graph about time and duct tape.
If all else fails, just ask yourself, "What would Sentinel do?" Obviously someone as brilliant as I am should be given a job. Don't go too far with the imitation, though. If you truly lie about being as amazing as I am, they'll reject your application and tell you to do important things instead, like being their family doctor, or run for president, etc.
