Why you should be building more than 1 business at a time
Peter Levels, (the founder of photoAI) was very clear about the fact that only 1 out his 99 business ventures actually succeeded and states "ship more".
My experience is the same. 1 out of 10 startups will actually work. Most will fail. This is why venture studios are so good. They find the best but constantly testing and trying.
You should be able to quickly get MVPs up and test which ones work and which ones don't. it should take an average of 3-6 months to test one business. If your customers don't bite, cut it and move on to the next one.
TEST AND TRY
Keep testing and trying to see which ones work. Ship fast and move quickly. It does not hurt to start 10 sites, hopefully one will work.
