Refusing to ask for help when you need it is refusing someone the chance to be helpful - Ric Ocasek
Rock star Alice Cooper can hire anyone to play in his band, and he only hires those he considers A-list players. But you can’t work in his band by simply by being the best guitar player on the planet. Cooper understands that it is just as important to get along off stage, so he picks players the band can tolerate spending time with.
If you lack expertise in an area, find partners with the skills you lack. Make sure everyone on the team is as passionate about the activity as you are and will not quit when you hit a bump. People like to help. Be sure to ask for it from those you trust; they will be supportive and not too critical. Ask as many as possible. You never know who might be able to help.
