popa- I actually hear what you’re saying. It really makes a ton of sense to me. Maybe that’s because I once (stil do?) have low self esteem.
and chein- I think I also understand why someone might rather it be an issue of self esteem rather than bad middos. If it’s bad middos then it says something about the person, that the person might not be a nice person or just plainly has bad middos but if it’s low self esteem then it means that they’re suffering (not sure if that’s the right word to use) with something that they themselves might not even know about.
