I have seen all aspects of business life; the good, the bad, the difficult, the politics, the government and the hiring and firing. I have done it for real for 25 years, had to live with every decision and spent time in every role. My knowledge comes from real experience, not from textbook theory.
Over 10 years I did everything; I dealt with the bank, funding, legal contracts, office leases, marketing, brought in investors, and diversified into new markets in order to survive and then grow again. I built it from a blank sheet of paper and sold it to a stock market listed plc ten years later.
If your Mentor hasn’t started a business, built it and then sold it, then they haven’t done it. I’ve done it twice.
