Something that has annoyed me for quite some time is when people first begin cubing and they are taught that having a better cube will make them faster. They spend an enormous amount of time buying 3x3's, lubing and restickering until they feel as though their cube is best. I never did this as a beginner. I was never picky about what cube or sticker shades, I found it to be a waste of my time. And in the long run I feel as though it has paid off for me personally. Why though? Well when I first began cubing I started on a dollar store cube that was pretty bad and achieved a 1:30 average with that in a few days and then I got a Rubik's store bought after that and used that for around 4 months until I was sub 20 with it. The stickers kept getting damaged on my Rubik's brand, but rather than buying new stickers, I replaced them with construction paper and tape. I'm not gonna lie, it was an awful cube. But what it taught me was to improve my lookahead and understanding of the cube if I wanted to get faster rather than relying on turn speed. One thing you also should keep in mind is that many cubers who are sub 10 today didn't start with the best cube. Maybe the best cube of the time but certainly wouldn't be a good cube by today's standards. So in order for them to get faster they had to discover new things on there own. We as cubers today are very spoiled in that we don't have to find out a lot of stuff on our own, there are many resources available to us to learn from and most cubers today think hardware matters and makes everything different when in reality when you just focus on improving your understanding of the cube, you will see improvement in your times. This is really just a giant blurb or rant but my basic point is. Learn to cope with subpar rather than pampering yourself with the best, so when you get the best you are the best.
