You didn't build relationships with your professional contacts just because you wanted people to party with. You did it because they might help you in your career at some point. But the way you ask for that help can kill the relationship. Here's what not to do.
Don't ask too much.
The surest way to get refused or ignored is to ask for so much time and effort, even your best friend would think twice about it. If you're job hunting, request a referral to a specific company, not to have your hand held throughout the entire process.
Don't ask at the last minute.
Nobody is obligated to drop their own agenda to take care of yours. Want an invitation to a networking event? Ask at least a month in advance. The bigger the favor, the more lead time you should allow.
Don't expect them to do all the work.
Before asking someone to help you write your resume, make sure they understand that you've already put a lot of research and planning into it.
Don't ask too soon in...
