Give yourself alternatives before circumstances force them.

Alternatives created under pressure are worse than alternatives created in advance, because you build them quickly, from a weaker position, with less choice about what they are. Building them early costs a little effort at a time when you do not need them, which is exactly why it works.

Spend a small amount of time this month on an option you do not currently require. A conversation, a skill, a small reserve. It is insurance, and it is cheapest before you need it.
