Rather than try nothing or trust no one and succeed at nothing, I try many things and trust nearly everyone and often discover very quickly what works and who can be trusted.
As long as you don’t exhaust all your resources in early experimentation, or trust someone with too much too early on, why not?
The fear of failure and the sting of betrayal are small in comparison to what’s gained when you put your focus beyond them. And by being ready and expecting them along the way, the effect is significantly less.
Live boldly. Death comes to all, whether you played it safe or dared greatly.
The key difference is in the kind of spirit you grew to become along the way.
