You're taught for knowledge, not experience, which provides you unexpected knowledge than those in textbooks and schools. If you want to know results before any experience you haven’t been through, by quoting other people’s experience, seeing it as a sample, judging it, calculating possible outcomes from it for yourself to “make decision” whether to experience it or not, it’ll mostly become excuse for you not to try it, or an obstacle for you to see what’s beyond an experience, because you miss the odds in it, which, are mostly surprises much better than what you’ve expected.
