> Keep sensitive data off of shared systems, use a strong password and Two Factor Authentication, keep your systems up to date, and be thoughtful about the trust you put into where you upload your data.

Also be thoughtful about the trust you put into who you share any data with (especially photos) and be conscious about who can see it (this is a big deal on social media, where privacy and visibility permissions aren’t easily understood or used by people). Unless you’re a celebrity (and sometimes even if you’re a celebrity), sensitive information could leak from anyone you’ve shared it with.
