Did he just hold that door open for you? Did she just make you a copy of that report? Did you just ask for another rush project?
Marketing is a demanding industry. Everything is urgent. And nothing is ever early.
'Please and Thank You' are part of my daily mantra. I never forget them, their omission is never an oversight and, conversely, their inclusion is always deliberate.
These simple words mean courtesy and respect. They demonstrate that you're thoughtful and aware. Also, these make you a great marketer because they translate into being both detail-oriented and big-picture-inclined.
Everyone deserves to be asked politely and appreciated accordingly.
This includes you, your coworkers, your employees, your partners and your customers.
