It is hard to drag yourself away from the computer when deals are happening!
Be aware that your cognitive abilities decline when you don’t take a break.
Sales people are often criticised for not paying attention to detail.
When fatigue causes errors occur at the quoting and contracting stages they are usually expensive to fix!
A friend of mine who managed a telco division was new to the job and was putting in many late nights.

Don’t fall into the same trap!
