Speed wins in horse racing, in down-hill ski racing, in The Indianapolis 500 and it will be the reason that you win in your business.
All things being equal, the first person who responds to a business opportunity will enjoy the business. Procrastination is the killer here … fitting opportunities into convenient time slots for you — this afternoon, on Friday, next week.
Finish what you are doing and get back to the caller, emailer, inquirer pronto. Speed wins. (You might want to tattoo this to your forearm.)
