You ask the client three extra questions not because you need the info, but because you're stalling

You've caught yourself Googling a formula for a technique you've done a hundred times

You weigh out the developer, then double-check the bottle, then double-check it again

You mix slower than you need to, because some part of you is stalling for more certainty

You've had your hand on the applicator brush and just... paused

You catch yourself thinking, "this looks right" instead of "I know this is right!"

You've posted in a Facebook group asking "what would you do here?" for something you technically already know the answer to

You've asked a coworker to "just double check this real quick" more times than you'd admit out loud

You've waited for someone else to walk by the color bar so you could casually ask their opinion

You've added "a little extra" of something — not because the math said so, but because you weren't sure

You replay the formula in your head on the drive home, even though the client left happy

You've screenshotted a "good" formula so you'd have proof it worked, for next time you doubt yourself

You've told yourself "I'll remember this for next time" about the same lesson, more than once

You still, after years behind the chair, sometimes think: "Am I actually good at this, or did I just get lucky?"
