Be suspicious of any success that needs to be kept secret from the people who love you.

Needing to hide it is information. The people closest to you are not harsh judges, they are the ones most likely to be pleased for you, so if you cannot tell them, the problem probably lies in the method rather than in how they would react. Concealment tends to mean you already know the answer. Shame is slow to speak and usually accurate.

None of this requires you to interrogate yourself about everything. Just notice which parts of your life you would rather your family not see, and ask whether that is privacy or hiding. The difference is whether you would be fine if they found out tomorrow.
