I'm not talking about your firm or department. I'm talking about you.
What are YOU selling?
Is it reliability? That's a fine product; nothing to scoff at. I'll take reliable over flashy 99 times out of 100.
Is it insight? That too is sorely needed but it can be over-rated. If you can combine it with reliability then your stock has really jumped.
Is it presentation? Some of us couldn't sell beer on a troopship. We need good presentation skills. Fold presentation in with the other products and you'll be on a roll.
Finally, how about persistence? Every day is not a fiesta. If you can take a punch and keep moving, you'll be able to put those other qualities into play. If not, they - and you - probably won't last very long.
