It&#x27;s something you pick up over time with experience. I&#x27;ve switched computers so many times over the last 20 years or so, I don&#x27;t sweat a sudden loss. Happened just last year, dumped coffee all over my MacBook Pro, had a brand new MacBook Air the next day, didn&#x27;t bother moving anything over except for one file I was working on that I hadn&#x27;t yet synced up.<p>I was back up and running within a couple of hours.<p>There&#x27;s this process that runs in my head whenever I work <i>on</i> my laptop. (as opposed to working on a coding project) I always keep in mind what the dependencies are, what it would take to replicate this if I lost it.
