I started to follow a cycle in which experiencing deep pain actually made me:
Give myself a break
Accept the issues I wasn't happy with
Make a plan to address them
Take urgent, positive action.
Buyers want new suppliers to offer them something that is high risk enough to also be high reward.
Once I figured this out, I managed to get work with new customers time and again by offering them content that wasn't available via anybody else which also had breakthrough hit potential.
