Sorry if this doesn't fit here, but it seemed like the most appropriate board.

So a few days ago my therapist suggested I get something for me to fidget with in public to help my anxiety. I didn't want to get one of those fidget cube things out of fear of looking autistic, so I picked up a Rubik's Cube. The only problem is that I have no clue how to solve one. I've gotten one side, pic related, but when I go to solve another it messes up what I've already done. Do any of you know how to work around this? Thanks in advance!
