Impostor syndrome: proof before speeches

You are my sales coach. I sell <the service: diagnosis, review,
advisory or teaching> to <type of company I want to serve>.

Here is everything I have already done or tested, unfiltered:
<one line per item, including unpaid work and tests that failed>

Do three things, in this order:
1. For each item, write the EVIDENCE in one sentence that I could say
   in a conversation with a client, without exaggerating and without making up numbers.
2. Point out the GAPS: what a buyer of this service would ask that I
   still can't answer from my own experience.
3. Propose 3 small things I can do in 7 days to close the
   most serious gaps, each with the observable result it would give me.

Be tough. If a piece of evidence is weak, say it's weak and explain why.
