I subscribed to a few newsletters that would send me startup ideas and problems to solve on a daily basis.

But somehow that didn't do anything for me.

Some even would offer to connect me to people with the problem, but I had the feeling even with people who would say "I have problem X and I'd pay for a solution" the whole process was still too abstract for me.

I think this has more to do with the business side of things than with talking to potential customers and implementing a solution.

How do I start? What are good first steps if you don't know anyone, don't have a network etc.
