I recently read the book "How to Fail at Almost Everything and Still Win Big" by Scott Adams. He worked in corporate America for 16 years and then created the Dilbert comic strip. He lists numerous businesses he has tried to start over the years with almost every single one failing. His main point was that he learned from each to make the likelihood of success of his next venture higher.
The book was inspiring because it showed how you need to just go out and try stuff. Each of the failed ideas he had actually seemed like they had a chance for success. For one reason or another they pretty much all failed. Those are the odds when starting your own business. I believe 8 in 10 new businesses fail within the first 5 years.
Knowing those odds it makes sense to take swings. Put your idea out there. Make a prototype. Do a Kickstarter. Put it on a website and try to start selling. The thought of guarding an idea for years to make it "perfect" is just nonsense. You potentially could've just wasted years by moving so slowly!
In reading the book you can tell that each of the failures was painful. Money was invested. Work was done. Partnerships were made. Scott was able to try his best at each and move on when things went South. He hit it big on his Dilbert idea though! All it takes is one.
I am mulling over a new idea and the book inspired me to look at available URL's, do some initial research, contact a lawyer about starting a new LLC and putting the idea out into the universe for people to give feedback on. Action is the only way that progress is made. I'm trying to keep that in mind and not overthink things as I get this next idea up and running.
