Entrepreneurial business favours the open mind. It favours people whose optimism drives them to prepare for many possible futures, pretty much purely for the joy of doing so.

Have passion for what you do; believe in yourself and your product and your customer; persevere; delegate; listen. Have fun. Today, I add: "Do good".

Explore this next great frontier where the boundaries between work and higher purpose are merging into one, where doing good really is good for business.

The best advice I could give anyone is to spend your time working on whatever you are passionate about in life.
