Sales is a transference of feelings
If you feel six foot an bullet proof you will attract clients and business in that same energy
If you are enthusiastic about what you sell and about your business you will attract clients and business in that same energy
When I talk to clients about hiring and keeping sales people I ALWAYS suggest they look for a couple of key things that typically underpin and support confidence
including the TYPE of confidence that makes for a great sales person.
Enthusiasm - everyone loves an enthusiast
Confidence - not like high ego bordering on arrogance but comfortable in their own skin
Culture fit - time and time again you see people who will thrive in one environment but be like a fish out of water in another
Attitude - kind of goes with out saying but it's SUPER important
Core Competence - don't look for a jack of all trades, simply identify the core competence and look for evidence of that
FIRST so you can treat anything else they can also do as a bonus.
Look for the above traits in your sales people and then ask yourself if you would enthusiastically re-hire each member in your team.
After all it's really hard to train yourself out of a bad recruiting situation but if you have the right team, the sky is the limit
