You make a descent point, but I don't agree.
If you just want to ski for a hobby then go right ahead. For some people skiing is a lifestyle; for others it's a way of life.
It is not SKIING itself that means so much to people but everything that goes with it - the freedom, the release, the environment, good company, and being able to leave your troubles behind.
I admit, some make it their way of life and see being a pro skier as the ultimate goal. Maybe they won't make it that far, but where's the damage in them trying?
By way of life, I don't mean that skiing should be what you live and die for. Because all things will pass. But, the lessons you learn from skiing can be applied to all aspects of your life.
Some people don't understand. What makes a professional is not his superhuman ability bestowed upon him since birth. It is his mindset, his state of mind that sets him apart.
At one time the professionals of today were no better than we were, so how did they get where they are at? Despite popular belief - it was not necesarily natural talent.
Yes, some have natural talent and that gives them a boost, but it only does so much.
What seperates a professional athlete from the rest of his pack is what he lives by. His dedication, perseverance, passion, and getting back up when he falls - that is what sets him apart.
In reality, the majority of us are all capable of skiing at this level; in fact, I believe the human body is capable of so much more then we can even begin to comprehend.
The reason why few ever get there is because few are willing to work their ass for it. Few are willing to ski when it's not fun, or get back up after a dramatic fall, few are consistant, few persevere, and those few are the ones we look up to. The ones we call professionals.
Ask any professional athlete, any truly successful businessman.. they will all tell you the same thing:
They owe their success not to luck, nor to natural talent, but to perseverence, consistance, and passion.
Don't listen to what everyone says in telling you that you can not make it, what makes them so wise on the topic? Have they made it?
Instead, listen to the people who have. They will all tell you the same - if you work for it, and never give up then there is no reason why you can not.
And after all that, let's just say you don't make it. So what? You can go home knowing that you did your best and that is success in itself.
Eat. Sleep. Breathe. Ski.
