I believe a disabled can make as big a success as people without disabilities.
The internet is now among us 24 hours a day as a new family member, and new features, increased performance and new devices pooping up almost daily.
If you have disability, internet has become an amazing tool to fast, inexpensive tailor a message, and then directly reach out to target groups, locally , regionally, but also globally if it is objective. Yes this was possible 30years ago but require an extensive and costly work effort and above all it took a longer time.
Number of people globally with disabilities who in recent years has become the online entrepreneurs increases exponentially. The internet has simply transformed what used to be almost unattainable, to be absolutely quite possible. So long as a disabled you have internet access and can manage a computer, then you can start, build and run a real online business that you own and have full control over, as long as your hands are working.
