The lessons

  1. Your first salary is the base of every number that comes after it. One uncomfortable conversation compounds for a decade.

    Read what happened

  2. If you can be replaced in two weeks, you can leave in two weeks. The cost of staying is invisible until you add up the years.

  3. A single client is not a business, it is a job with none of the protections. Keep selling when you least need to.

I let one client be 80% of my revenue

🇪🇸 Spain · 💼 Career · 30-39

What happened

It was comfortable and I stopped selling. They restructured, my contact left, and the contract ended with 30 days notice. I had no pipeline at all.
