Be around like minded people. If I knew how to do the work but couldn't get the work I would get around the people that can get the work.
I would be asking the people who can get the work for their time, offering my labour for free, to see what they do differently.
I would be asking how, what, why, methods, marketing, looking at their approach, people can see confidence and if YOU don't think you are going to get work when you are quoting then you wont get it.
Positive, positive, positive
