Great innovation rides on the shoulders of others. Whilst chance plays a role it is powered by enthusiasm.

The time to market or ‘valley of death’ may be long and frustrating but the journey to success is for many both liberating and full of learning.

Sure chance, technology, market demand and market timing allow great ideas to flourish. But persistence pays off, even if the mature marketable idea turns out to be very different from the original concept.

In this sense, good ideas are as precarious as new life but somehow we all expect to live into old age knowing that the journey will often be unpredictable. Things just happen.

In the same way, every idea like every living thing has its own spark.

Listen as Steven Johnson, an innovation guru, entertains you in this short video trip through the evolution of good ideas.
