Oh yes, I know that one. I wrote a blog post about how I personally deal with 1001 business ideas: hustleup.io/too-many-business-ideas
The essence is that I keep some limited, time-boxed experimentation space (around 10-15% of my time) to try out and work on new "shiny" things.
The other 85% of the time, I focus on one or two ideas max to ensure I make progress.
