We need to find an idea that cant be saturated and post it up on here.
Ever heard of a product life cycle, for now lets just call it the "life cycle" as it exists for almost ever idea, innovation or service, let me not get into a full explanation (too time consuming, just google it).
Ok so in a nutshell, in our context:
1) In the early stage the idea is little known, some people may know about it, there is little info available.
2) as it grows some people will mention it but you need to think and figure out most of the details.
3) Someone decides to bank on the idea and decides to release an e-book or some sort of training. this would be a maturing/peaking
4) We start talking about it on BHW, we announce it everywhere every one seems to be doing it and finally we hit the saturation threshold, the process of declining starts and the demise.
But keep in mind its the demise of the old idea not an evolved idea, there is always a lot of different ways an idea can evolve, a few people remain ahead of the curve they may form a jv,usually they fly solo and these are the people/individual who form the first point.
Anyways getting back to my point, find an idea, add some value and keep moving forward, keeping adding value, if you are waiting to find "an idea that cant be saturated", i'd like to say "forget it and give up" but then you may get lucky, let exchange notes on how that goes in a few years.. maybe a decade.. what do you think?
Cheers!!
