You do not need to be 100% man (or woman). 80% is usually enough.

In the Internet, the printed magazines, the literature, and also within the common knowledge you can find hundreds or thousands of lists of things that 'real man do', or 'real women do not do', etc. Even on this blog there is an example - the advice that Don Quixote gave to Sancho Panza in the masterpiece by Cervantes.

What is my attitude to such guidance?

First of all, these pieces of advice are usually right. Some of them may not be appropriate for our times, some for the culture, some for the social position, but in general they preach the universal values that a happy and balanced society is based on, including the happy and balances relationships between a man and a woman, a boss and an employee, a parent and a child, and so on. This is why reading them is, in almost in every case, very commendable. I cannot go wrong by reading what other people thought and decided to leave as advice to others.

And how much of that do I need to implement on your life?

I cannot accommodate everything, as the pieces of advice are sometimes very specific and personal. This is why relying solely on one source of such life wisdom is not necessarily a great idea. What I  do is looking for common themes. Comparing the contemporary ones with the old ones, and getting be surprised with how little the things have changed over the years. Comparing the ones from various cultures, and being amazed how many common themes exist. Comparing the ones written by men and by women, and again getting astonished that, with all the differences, we see so many things in identical ways.

Whatever is a common theme, it is probably worth accommodating. Whatever is not, shall be approached with caution.  About 80% is the former, about 20% is the latter. Therefore, if I am reading about the 100 things real men do, I will likely go for 80 of these.
