Your writing is great man, I think your book would be very refreshing. 100% would support.
Oh and I’d love to hear your thoughts on how you deal with competitors. How you considered them when first entering the market, when you put on your horse blinders and stick to your product/project vs. legitimately taking heed of other products that accomplish similar goals as yours.
In my case, I started developing a product to empower guest communication at small businesses in the hospitality industry (think hostels, bed & breakfasts, Inns) via real time and automated SMS. (shameless plug: http://helloconcie.com) But as I started really diving deep into forums and even engaging in conversations with people directly, I found that there exists such a tool already and they seem to be way ahead of me (I’m a bootstrapped self imposed-masochist like yourself). But then I think to myself, hey this industry is HUGE and why isn’t everyone using an sms-based tool, all the big guns are (Marriott, Hilton, etc.). Maybe there’s plenty of room for my product since the majority of small operations don’t even use such a tool yet.
Anyways, would love to hear your thoughts and I hope you go through with the book project!
