Ask for advice, not help. Asking for advice provides the opportunity for someone to demonstrate value and feel good about themselves.
Asking for help is just asking for something and doesn’t have the guarantee of anything in return. Next time you need something ask someone you think might know if they know how its done, you never know they may just jump at the chance to demonstrate their skills and help you you out.
This ties in with the age old advice of if you want to do something find someone who already did it and ask them how it’s done.
