A wine sales job doesn’t involve rocket science.
Nobody is going to die if you screw up. There really aren’t that many moving pieces. Keep it simple.
Be consistent in doing what you say you’ll do.
Be consistent in who you meet with, and how you run your meetings.
Be consistent about your goals, both for yourself and your clients.
And always seek better customers, both for yourself and your company.
You’re not trying to design a ship to go to Mars. This is fermented grape juice. Don’t complicate things.
(PS: Seeking better customers may be the most important thing on this list.)
