Did you ever play with a Rubik's cube? I did. It was a frustrating adventure that I loved to hate.
Days can be spent working on this to get all the colors on each side to match. Days! It annoyed me when I used to get four sides correct, but two sides had a color which belonged to the other. Grrrrr.
The thing is once I learned how to complete it, it wasn't as difficult to do it again. Over the years I've found that life is just like that. The first time you do something, it's hard as hell, and rarely ever fun. Things get easier the more you do something.
That's the lesson of the Rubik's cube. Try, try, and try again. If you can't ever get all of the colors on the correct side then do what a friend of mine did and remove the stickers and put them where you want. Is that cheating? Eh! Some might call it thinking outside the box.
I loved the triangle version. I found it easier to complete and the shape just tickled me.
