Right... So it's unfair somehow to point out that 19 is old enough to know how to look up some videos on YouTube? Or that a 19 year old these days statistically watches more YouTube than actual TV, but somehow this one never thought to pull up some snowboarding?
Honestly, I get the same thing at the gym all the time. "Well, I might know how to perform XYZ movement if someone would be willing to show me"... As if it's everyone else's responsibility to inform others how to do something. Take some responsibility, show some effort and gumption, and do some research yourself prior to asking easy questions. Don't be intellectually lazy.
This is actually helpful, if one can get out of their own way to see things properly. Many, many of the life changing conversations that have occurred in my life were geared towards my own (at the time) shortcomings. Be mature enough to see the truth in them and one will be better off 100% of the time.
My advice: put some personal effort into your desired outcome by reading / watching everything you can on the subject, inclusive of reading through every old thread from this very forum. Then ask questions. At that point, and I truly mean this, you will not be wasting anyone's time and will make many, many friends here (including me).
