Solving 'real problems' is hard. Some categories 'real problems' often fall in to: 1. Problems too trivial to expend energy and time solving once and for all. (It's easier to pay the small cost each time you encounter the problem). Not marketable. 2. Problems you can solve, but everyone else already have partial or 'good enough' solutions for. Competitive, no innovation. 3. Problems you think you can solve, but you really can't. Doomed. 4. Problems you know you can't solve on your own, or with the resources available to you. Expensive. 5. Problems outside of your area of expertise. 6. Problems you have, but really aren't problems to anyone else.
