We all have different guts and understanding your personality, which part of your guts you can trust and with which one’s to maintain a more sober relationship with is a very individual learning journey in my experience.
Only trusting your gut is probably as bad a piece of advice as saying ”never trust your gut”.
The gut was evolved through millions of years of evolution. It’s optimized for a different life style but this doesn’t necessarily mean it’s always wrong.
Don’t always obey your gut. But listen to it and make your own judgement. Sometimes it tells a hard truth.
