You decisively missed the point. Yeah indeed for sure fear can be overcome by simply doing it successfully for the first time, but in order to actually be successful you need to prepare, always without exception. I'm sure you had prepared yourself for all of that, motorcycle classes before you got your bike, skydiving lessons before you were in the plane with a reputable pilot and instructor, leaving the Minecraft t-shirt in the wardrobe before offering a date. Good for you, but you didn't succeed just because you decided to. You did because you were prepared, and you were prepared because you were afraid from the beginning. If you followed the advice in the image to the letter, you'd have thrown yourself out of the plane afraid, but confident in your ability to figure out the parachute. Fear is necessary to hold us all back from recklessness.

I do think you're right. Some people certainly are too scared. The advice to simply do things regardless of being scared just isn't helpful or motivating to those people though. It's a real succinct-looking message, but it doesn't help them actually deal with the fear. Fear can be paralyzing and disabling when you least want it to be, just an evolutionary flaw. Overcoming it takes a lot of reasoning with that fight-or-flight part of the brain to flip that switch all the way towards fight. And I'm not talking "mad-scramble-thrash-and-flail-for-your-life" fight, I'm talking "kick-ass-take-names-and-make-a-name-for-myself" fight. Nobody that holds your attention does so with fear in their eyes. He or she does it with a plan behind them, and with knowledge and skills further back in their head. Success isn't just manifested and neither is confidence, both are borne from preparation.
