Should you wait until someone shows responsibility to give them more
Should you give them responsibility to grow them up into it?
Really, neither is right or wrong, but they do come from different mindsets. The first proposition really takes into account the overall safety of the venture. There is very little risk involved for either party. The latter requires that both risk. It may not work out well.
When I was younger, I definitely employed and preached the first; now that I am older, I feel like I might lean more toward the second. Because sometimes people don’t know what they’re capable of until someone trusts them with something. Whether they succeed or fail, either way, hopefully, they will grow. And growth seems more important than safety. Usually, they are in opposition to one another.
