I heard some of the most powerful advice for any growth oriented executive or salesperson:
Just because you can't sell anything right now, doesn't mean you can't be useful.
The best companies, and the ones who are going to get through downturns stronger, are the ones that focus on being useful to their clients, customers, and prospects first, with making a sale coming in a distant second. The amazing thing is that the more you focus on being useful to someone, the more often, and the easier, you make sales.
