It works

But only as much as you work it:

• 10 cold calls, or 1,000 cold calls. Is it the technique you use, or the consistency you bring, that makes the most difference?
• Doing an experiment, or doing yet more research. Is it the extra research you do, or the real-world experience you earn, that makes the most difference?
• The best talent, or the big mission. Is it the skills you have, or the drive to keep going that you bring, that makes the most difference?

Sometimes the difference between successful and unsuccessful teams is that one of them just got on with it.
