As a working professional life can get pretty stale/boring... especially when we get caught up in the monotony of our roles and day to day activities.
I feel like sometimes sales has periods where you feel on fire, you're excited, motivated and crushing it (or getting there)... BUT on the flip side, there are times where ti feels blah, you go through the motions, and you might not even feel like doing the work.
How do you overcome the mundane tasks, going through the motions, and getting over the hump? How do you make everyday feel different?
The same is true for sales. The best reps I've ever worked were relentless in finding ways to get better: they listened to their calls, read books, prospected endlessly, ensured their SFDC was up to date on weekends so their week was free for selling, took the initiative to get training on their own, etc.
You have to view your sales skillset as something to be honed and tuned. The monotony is where the millions are made :)
