I’m not sure I agree with this advice though I have no experience with being blind. Possibly creating/selling products/running a service would be a good way to have an income stream which is reasonably sustainable but I would worry about any graphical front end to any software product, and my general worry would be about loss of income because my expectation would be that finding a job while blind would be hard. I would expect working for a large tech company would have two advantages: 1. This would likely be the most reliable easiest way to actually build up a decent amount of capital; and 2. I would expect a larger company would be more accommodating of your going blind because they would be much better able to cope with a loss of productivity and adjustment period and they may be more nervous of the legal risks of not supporting you. If you run your own business or work for a company with little spare money, it will be much harder to have a loss of productivity or adjustment period.
