Capability is freedom disguised as skill.

Every skill you have removes a dependency. It means one fewer situation where you have to accept someone else’s terms, wait for help, or pay whatever is asked. Freedom in practice is often just the accumulated result of being able to do things yourself.

Look at where you currently have no choice but to rely on someone. Pick the one that constrains you most and learn enough to have an option. Skills bought that way pay for a long time.
