People don't care what you know or what you can do until they know what you have already done that has produced a positive, measurable result in what they're looking to do for someone like them.

If you haven't already accomplished that, then saying you can do it when you haven't will require you to b.s. and do some fancy tap dancing which anyone with half a brain will see through.

What's the solution?

1. Step 1 - Think of what you have already done that produced a positive, measurable result for someone other than yourself.  

2. Step 2 - Step back and think of who or what company urgently needs what you have already done.

3. Step 3 - Think of how you can get in front of those people who will recognize and need the value of what you can offer.

For instance, I have an ability to identify, speak to and help people deal with the elephant in the room that is preventing them from moving forward.  I used to do that when I would do house calls to dying patients and their families and help break the log jam of unresolved conflicts.  After successfully doing that I thought, "What are situations where there are similar unresolved conflicts and time is running out?"

That openned the door to meeting with executive teams and management teams that were going through be transitions.
