I view interpersonal trust like a ladder. You trust a little, if someone trusts you back or validates your trust, then you can progress to trusting more. If not, don’t!
As far as institutional trust, you’ll have to decide for yourself IMO. Do you agree with the messaging from the institution? Do you generally trust the people within it? If so, progress, otherwise don’t.
If you have a different question let me know. Hope this helps.
I keep most of my “EDC” stuff in my bag — chapstick, keys, hand sani, etc.
If I’m going out for a while and I expect it to get dark, I like to pack a flashlight.
I used to carry a knife but sometimes it makes going into bars and clubs awkward so I usually leave it at home now
