i have been in the foreign trade circle for several years. i found that many unsuccessful salesguys has a weakness in common. their first response to his failure would be to find some execuses to avoid his responsibilities, but not solution to solve problems. that's why they always lose.
being a salesperson, he should have courage to face his failure! don't you think so?
That is true,I also found excuses for my failue,now I will face the difficulties and slove them!
