1. You need to earn trust
My father loves me, but when I first took the job, he kept telling me how he had always been the first to arrive and the last to leave. I kept thinking how “20th century” he was, so I decided to show him how, in the 21st century, “you can do it all”, i.e., work and have a life balance. What I hadn’t understood was his underlying message: he was expecting me to earn his trust by working hard; if possible, by out-working him.

2. You must have (some) shared values
In addition to earning the trust of your family forbear, you must understand the core values of the person you need to impress or make an ally of and prove to them that you share at least some of them; they will esteem you even more.

3. Let them make mistakes
My father always told me he saw his mission as a father as staying on the lifeboat just a few meters away from his kids, ready to support us when we were hit by a wave. Of course, he could see the next wave coming. But as painful as it must have been for him – and even more so when it impacted the business he founded – he’d still let me charge straight into the wave. After all, we only really learn by making mistakes, don’t we? And every time, he was right there, helping me catch my breath and keeping me (and the company, incidentally) from drowning.
