No ones said that aptitude tests equated to gaining experience in a field.
Also, you're the person that's going 'we must mindlessly follow the test'. I've never suggested anything of the sort. But hey if people like that are dumb, well it certainly fits you.
Right. We should just 'go out and do something'.
Oh shit, it requires commitment, time, effort, and an education.
So, according to you, if you think you might like something, you should go to university, spend years studying it, get your degree, rack up debt, get an internship, spend further years working your way up into it, and surprise you hate it.
You don't disagree with me on principle, you just have a dumb caricature in your head about what basic career guidance entails and it's making you say dumb shit. Example, I've never suggested that 'the internet is your teacher'.
A proper personality/aptitude test is a very useful tool for figuring out shit that might fit you. Note that I said tool, not whatever the fuck you're imagining.
If more people, especially young people, spent a modicum of time doing proper career research, instead of talking to people like you who's advice boils down to 'uh, just like, you'll automatically stumble into whatever fits you, it's like uh, destiny, uh, also don't ever take medication, it's better if you die' you'd have a lot more people finding their place in life.
