Most of us cube for fun. But don't really get any monetary profit unless you are part of high end competitions. I recently went on a trip and as usual took my GuHong to practice. I average at sub 40 and someone on the plane was asking me how fast i could do it. (I'll take this time to say it makes me laugh so hard when people say they've only solved 2 - 5 faces of the cube. It makes me not take them seriously ).
Anyway, so I said I could guarantee him under a minute. The Tall rich dude said if he wanted to bet actual cash.
I acted as if I was insecure about my timing and said "ok, 20 bucks".
So he made his hot girlfriend scramble it. And handed it to me. And i finished at about 30 seconds, His timing. Besides earning 20 bucks, I caught the attention of a small radius of people around me inside the plane, which is pretty awesome.
Additionally I just realized that this infamous puzzle is pretty much considered a challenge to most people and those people usually categorize us (cubers) as abnormally smart.
Having this thrill I went to a Swatch store. My dad was holding my cube when the manager asked my dad if he could solve it. After they negotiated, the manager scrambled the cube gave it to me and again, solved it in about 30 seconds. After a brief applause I courageously said, "OK, so what does this mean, do I get a free watch?". He replied with a chuckle and then intimidated by my skill (which we all know isn't as great as sub 20's of sub 15's) he granted me a 10% off any purchase.
So for all you cubers out there, many who are better than me, take this skill to the world and If you have the guts, squeeze some money of of it, or just do it to have fun. I always see myself attracting tons of attention when I have my cube!
