One way to define power is in terms of options.
The more options we have the more power we have. The better the options we have the more power we have.
It is the wide range of options that allows us to be adaptable. We have the power to choose the option that is most going to serve us.
When planning, take options into account. If you have two different paths you can take that each has an outcome, take into account what options you have at the end. If on one path you learn a new skill along with an outcome that is close to the other path, it might make sense to take the path where you learn the new skill. On this path, you have the outcome as well as the options that come with the new skill.
