Getting help involves giving help.
If you need help with a job or project, those you look to for help need to know that you'll help them when they need it.
You can also employ an element of barter.
Help me with the clutch and I'll give you a free oil change.
Who among us doesn't have some FAR oil in the appropriate grade for just about anything and probably a filter as well?
Or maybe, I'll help you do your brakes?
If you want help, you have to offer it as well.
If you've already done this and your friends still won't help you, then you need better people as friends.
