The best thing about cubing is that 99% of the world thing it's such an impossible thing to solve..and that's where all the benefits come from =) well except the money-making part that is...
I agree with the 99% of the world think it is impossible...so you are someone special if you can solve it...and even more special when u can solve it in a very fast time...
Some girls said that it is a good thing to do...trains the mind and stuffs...I told them it is more related to speed and reaction..not much thinking...but nobody agrees with me...(I am talking about non-cubers)...they still think I am very smart or good in math to solve puzzles...
You will get famous and many people will know you...once a while I will go back to my ex secondary school...and many ppl knows me...but I don't even know them...gain popularity by cubing? I guess most ppl won't like to be an ordinary person right? Being someone special from the others is quite cool...
Yup, I find it as a topic starter...I already have lots of friends before I even started cubing...now I even have more... but ya, you will get cuber haters too...which think you are a freak...but I won't care...because I don't even to them much all the while..

for my close friends...well..I don't really cube that much..I only cube when I am free...
You get to mix with cuber friends...yes, travel too...I only been to Singapore once when I was young...nvr had a chance to go there anymore after that...now after cubing, had a chance to go to Singapore because of cubing competition...
I cube when I am walking in shopping complex...eating(waiting for food to arrive)...in the bus..in the train... most people just sit and wait when eating / in the bus or in the train...you waste more time by just sitting there doing nothing...but if you spend like 5~10 hours cubing..then I can say yes, you are wasting your time...because I doubt you have 5~10 hours of free time everyday...I only have like 30 mins~1 hour+ free time everyday..(it is a good past time during school holidays / semester breaks / public holidays)
and most of my time spent when I am at home is...online..chatting...surfing net...youtube...forums...listen to music...it is a waste of time too...so when I totally have nothing to do then I will solve puzzles...
I lost interest very fast...so keep buying new puzzles to test out myself...nowadays I like to solve puzzles without finding out solutions...coming up with own solutions is much more fun...testing your puzzle solving skills...not by learning from others...
You can earn part time income by promoting and selling puzzles or helping other lube their puzzles or modify their puzzles and charging them a small price...
I noticed that most puzzle sellers aren't cubers or are not good in cubing...they have hard time promoting and also don't even know how to find good quality puzzles to sell...
Well the good things about cubing for me have been:
1.Better hand eye co-ordination
2.Made me think more logically about puzzles
3.It's very impressive and can change the mood of a group of people easily.
Bad points:
1. Get called a nerd
2. People say your cheating
Yup...better hand eye co-ordination...
Yes..some ppl think I am a nerd...(for those that don't know me of course)...for those that know me, nobody will say I am a nerd =P
but why cheating? I don't think anyone said I cheated before..I don't get it...how come it is cheating?
Benefits :
2 handed solves - train double hands speed and reaction time...lookahead too... you can apply reaction time and lookahead during daily lives... like example writing and typing...I never thought of looking ahead before in my life when I do these things...now I always lookahead...so I improved in many daily life-related things...
1 handed solves - make that particular hand more good in grabbing, holding, gripping... seriously speaking..last time I can't type sms with one hand...after doing right hand solves... my right hand is able to grip my mobile phone much well...and can type sms using one hand...and won't drop my mobile phone on the ground...I still cant handle mobile phone with left hand alone because I nvr train cubing with left hand...
normal blindfold solves - improves memory...like someone wants u to memorize a long sentence and saying it out after that...normal blindfold helps you in it....you will find it much easier to memorize things in a fast speed...
multiple blindfold solves - makes you able to memorize lots of things...but not in speed....
solving various puzzles - makes you able to think logically on how to solve new puzzles(iq type)....I like to solve various puzzles...and I come out with a method on how I learn all my puzzles.... (steps : investigate mechanism>get used to mechanism>test out all of the previous puzzle methods and try to figure which concept is related to the current puzzle(if not, then figure out urself intuitively)>come up with solutions>improve the solutions>make it into a method>convert it into a speedsolve method(if you are willing to spend time)>teach others(if you are willing to share)
feet solves - train your feet dexterity? maybe even able to grab objects with feet? well I don't know, because I haven't try feet cubing yet..
big cubes speed solve - train your ability to find objects easily...like if there are many small parts in an object..you can identify them much faster..
