When trading, it's normal to look at others' opinions, but when doing so, pay attention to how this person speaks and whether they have a complete logic.

An effective analysis must be based on: whether the current position is at a high or low point of the cycle, whether it is a specific month, whether there are clear known major bullish/bearish factors in the near term (determining whether it makes sense to establish a position in the short term), whether there are clear known major bullish/bearish factors in the medium term (determining how long you might be trapped at most), and then the entry point and potential support/resistance levels.
If a certain teacher's analysis only has dry "xxx long, xxx short, take profit xxx, stop loss xxx", then you might as well not read it...
Even worse is the kind that brings in a lot of subjective speculation, for example, the entire text is full of phrases like "I think", "I feel", "approximately", "possibly". When these become catchphrases, reading it is worse than not reading it.
Also a little-known fact: those who don't say "long" but say "duo", don't say "short" but say "kong" – they are either scammers or manipulators, they will never be wrongfully accused...
When you get burned, remember how you got burned. Carefully recall who it was that shouted at you to go long at the highs, kept shouting at you to buy the dips as it kept falling, and kept shouting at you to go short as it kept rising.
Also remember why you missed the boat each time.
If you can lose and understand why, then the money lost is not entirely wasted; if you lose but don't understand why, then it's wasted...
