There is definitely something to be said for being yourself around women.
As compared to pretending to be something you are not it is an infinitely better approach that will earn you greater popularity with women in general.
Yet this realization is not beneficial if it is taken to the extreme.
While acting as you normally do should just as readily feature into dating women as it should in any other part of your life, be careful not to use it as an excuse for the following pitfalls.
It should not be a euphemism for avoiding self-development.
Do not brush off criticism by saying that it is just who you are, as in doing so you merely showcase your inability to adapt to people or situations.
Suffice it to say that women will be more impressed with men who are not only confident enough to accept their flaws, but also care to address them.
Nor should it be a reason for getting stuck in a rut.
While some measure of routine in life is not necessarily bad, women might easily get bored with or lose interest in you if you are never up for trying something new.
After all, mutual fun is perhaps the most important ingredient of any successful dating relationship, and getting out of your comfort zone together, although intimidating, is conducive to just that.
On top of that you will probably enjoy life far more than you would by limiting yourself to what you are already familiar with.
In other words you may by all means be yourself when you are dating women, but if you want to be successful at attracting and retaining the ladies you should not treat your 'self' as permanent and unchangeable.
Be whoever you want, but devote yourself to being open-minded and willing to experiment regardless.
