Don't worry, @brianna.vanvalen It really is easy. When we boil it all down, the simple fact is that your screen's brightness needs to match your prints.
The HUGE thing you need to overcome is the feeling, at first, that your screen is way too dim. Everyone feels this, don't worry. But I promise, it will only take a few days before you're used to it, and in fact you'll wonder how you ever tolerated it so bright before!
