This is good advice to start out with.
After you get used to trusting yourself,
you can reasonably decide to place trust in another.
Discussion
i trust several people more than myself
how is it possible to really have trust in anyone?
if you dont trust the one who places the trust in the first place?
Once I trusted myself, I learned to understand protocols by reading the source RFCs, specs, whitepapers, etc. Prior to that it seemed like a dark art that was beyond me.
The first one is the most difficult. I recommend starting with RFC2119
https://www.rfc-editor.org/rfc/rfc2119
Now I can figure out for myself how much to trust a protocol.
Yes, Trust yourself.
