When you are trying new things, looking for innovation, improving your product or service, fail is part of the journey. 

If you are not failing doing things differently to give more value to your customers, then you are letting your company die, because our world is changing faster than never, the market is looking for constant innovation, improvement and new suppliers out there, your competition is getting better and fighting for your market share. So don’t be afraid for failing, be afraid for being still.

Just to give you an example of what it takes to succeed, see image below where you can see Howard Rogers (Chief Chemist) and his team showing the 5000 bottles of chemical compounds used to discover the Polaroid colour film process in 1963.
How many combinations they tried? how many times they failed? 

Behind every success story there are thousands of failures.
