Knowing what to do is great. Especially if you are in an advisory role such as a mentor or counselor. Knowing how to do is better. That way, if you need to take action, you can effectively participate. Being able to do and deciding to do is nuanced. Sometimes, it is better to not get involved and allow the team to figure it out. This is where knowing, doing, and wisdom intersect. Having a keen sense of the stakes involved and enough self-awareness to know when to do and when to not do is potentially significant.
