The concept of “selling” can be intimidating. So it helps to break the process down into steps.
First, figure out all the necessary precursors to a transaction.
Then, map out a repeatable process that hits all these milestones (also known as a pipeline), and test the process out.
Especially in the beginning, pipelines can be "leaky".
But with each "leak" that gets patched, things become slightly easier the next time.
Then, it’s just a matter of removing the current bottleneck.
It could be a skill deficiency, unnecessary friction, an unaddressed concern, or all manner of other things.
The tactics will vary, but this fundamental process never changes.
