In life, making adaptations is always necessary based upon the context of the situation. The danger is completely deviating or discarding your principles and character in order to procure a situation of minor benefit. One such example is donning a new completely new personality because you feel 'that's what the women want.' You don't want to metamorph into some wannabe bad-boy because that's what some broads like. What you DO do is alter how you apply your positive characteristics in order not to be taken advantage of.
For example, you might have been a guy who was quick to take women out to dinner because of your generous nature, but it's well known that a lot of women abuse that generosity for their selfish benefit. Now instead of completely discarding your generous nature, you will change how you approach that situation. Instead of taking out a woman you just met to dinner, you will save that generosity for a woman who actually deserves it and has showed you that she likes you without regard to your material status. In other words, you will qualify her first, but after she has qualified, then you will show her generosity given she can appreciate it.
Jesus said in the Bible, Do not toss your pearls to swine, lest they trample them underfoot. In other words, do not give your precious gifts to those who are unable to appreciate them. Generosity is a gift. If a woman is unable to appreciate my generosity, she will no longer be able to participate in it... Do not cast aside your positive characteristics because 'that gets the hoes.' Just alter the level of that particular characteristic that you show to the woman you are dealing with to see if she can appreciate what you are doing or not.
