Please pay very close attention to how Mint expects you to manage software. I haven’t used Mint in a very long time, but they should have new user docs that cover this. This is my advice for any distro (though there are some commonalities) - noobies can save themselves a LOT of headache if they take some time to be sure they understand how that distro expects users to manage software.
My second piece of unasked for advice - Mint-specific forums will be much more useful for any support questions you have than general Linux forums during the time when you are getting your feet wet. There are a lot of things that are the same between distros, but enough differences to make distro-specific advice valuable for new folks.
