Can I undo this if I turn out to be wrong?

I’m deciding whether to . Break it into the separate commitments it involves, such as money, contracts, relationships, reputation and time. For each one, tell me whether it’s easy to undo, costly to undo or permanent, and what undoing it would actually take. Judge by what undoing it would cost in practice, not by whether it’s technically possible. Put that in a short table. Then tell me which single part deserves most of my thinking, which parts I can decide quickly and adjust later, and what I’d want settled before any step I can’t take back. If how reversible something is depends on rules where I live, say so instead of guessing.
