Funnily, this guide can apply to itself, lmao (self-referential).

Is only one option "the right one" and every other option is wrong?

1: Yes, there is only one right option, and every other option is wrong.
2: There is no "objectively" right option, but there is one that is right for you, and you must find out what that is and choose that one. The other options are all wrong for you.
3: There is no "objectively" right option, but there is one that is the best for you, and you must find out what that is and choose that one. The other options are:
3.1: Not "wrong", just bad.
3.2: Neither "wrong" nor necessarily "bad" (though some of them may be), just not the best, not optimal, let's say.
3.3: Some of them may be decent or even good, but not as great as the best option that is out there for you.
4: There is no "objectively" right option, but there is one that is the best for you, but you can also choose one of the less good options, as long as they're good enough, it doesn't have to be the best one.
4.1: If there's one "best" option and a bunch of less good but still decent ones, choose one of the decent ones. There are surprising benefits of choosing a sub-optimal option.
5: There is no "objectively" right option nor one that is best for you, there are various good options (as well as bad ones that it's best to avoid) that all have their pros and cons, no option is perfect, they all have compromises and trade-offs, but it's good to make a choice, it doesn't have to be perfect or a panacea.
6: The "synthesis" (i.e. the mix of all ideas simultaneously, often leading to extreme skepticism, apathy, emptiness, indifference, relativism, nihilism, neutrality etc) is what should be considered. It's not a good thing to have your own opinions, as they lead you to biases and narrow-mindedness.
7: AVOID the "synthesis". You are a human being, it's okay to have your own opinions, you are a part of God, not God, you can't be neutral towards everything. You are just a human being.
8: Neither avoid nor seek the "synthesis". Whatever you feel it's the most natural option for you, go with it. There's nothing wrong with being "neutral" in respect to certain things. Sure, you're just a human being, but a human being is capable of feeling apathy, indifference, emptiness and all that sort of stuff. Those are human feelings too. There's no need to have an opinion about literally everything if you don't feel like having one. On the other hand, it's also okay to be opinionated. Again, you're just a human being. Yeah, "confirmation bias", "narrow-mindedness", being "dogmatic" and all that sort of stuff... those are human characteristics too. Whatever feels most natural to you, go with it. Don't worry. Actually, worrying is okay, too (:
9: There is a "best option", but you must NOT choose it, as perfection is the enemy of good. Choose one of the many sub-optimal "good" options.
