Good question!
Create my own organization, organization that focuses on uniqueness of Autistic mind not on some inevitable doom. I would try to provide information about the newest or the most effective therapy methods, nutrition, ways to deal with sensory issues. Information has to be presented in form that's not confusing for anyone.
I would definitely organize an Awareness campaign, but it has to be highly entertaining, active, loud. I would organize various events for different types of people.
Of course I would have various products to sell and raise money that way.
I would create tv shows, that are not depressing and misleading but inspiring and entertaining, I'm not exactly sure how it works, but I would get them running on major channels, and at some point I would have a channel of my own...
we're dreaming here right? ...ok next
Where the money goes: 1st - what I think is absolutely crucial nowadays - educating health professionals, social workers, teachers etc but most importantly parents of individuals with ASD (Aspergers, Autism etc) in new, the most effective therapy methods and so on. Massive workshops for parents have to be created, I think it is very important.
I would also try to support a research, where focus is on getting adults with autism out of their "shells". I personally believe, therapy can not only work for kids but for some adults as well (I'm talking about more or less low functioning ones right now).
I would try to provide apps for different devices and make them available for individuals with Autism, together with devices themselves. Who knows maybe I could sign a contract with some factory in china or something and make android based tablets and create android apps, so we wouldn't have to spent tons of money on iPads, unless Apple and some other companies would be willing to give discounts.
I could come up with dozens of ideas what I would do. Maybe one day I would be able to make at least a part if it happen... Who knows, it's hard to say at this point. Right now I'm just dreaming.
