Never complain; never explain.
This is an old saying of Ben Disraeli, a British Prime Minister from the 1800's. These words ring true for life in general, but especially for whatever interactions you choose to pursue with women. I'll break it down.
A. Never complain.
1) Because it solves nothing. As my grandfather used to say: "If you can do something about it, don't bitch. If you can't do anything about it, don't bitch."
Men define themselves by their actions, not by their words. Actions will fulfill you. Mere words will not. Saying you'll lift gets you nowhere. Saying you'll read a book gets you nowhere. Lifting that weight, or actually reading for an hour, will get you somewhere.
2) It's a womanly/beta habit.
There's a reason they call it "bitching." Unlike men, women have no problem seeing words as an accomplishment in of itself. That's why many of them, for example, can leave a gym feeling fulfilled because they chatted for 30 minutes with so and so, even if they did almost no exercise.
Also, women whine and complain partially as a means of verbal processing, but mostly as a way to vent their weaknesses and insecurities and receive social validation for it. Betas do this too. There's always someone to blame for their problems (besides them), whether it's their fathers, society, the elementary school they went to, the food industries, their anti-anxiety medication, their porn addiction, etc.
Don't buy into this. We've all dealt with various challenges in our lives. Accept it and fix it however you can. Got childhood trauma? See a therapist. Too fat? Watch what you eat and workout. Just shut up and solve it. You don't need someone else's validation or faux-pity. Whining about it simply makes you seem weak, which drives anyone (especially women) away.
Remember, a key part of TRP strategy is being confident and "holding frame." You cannot do this if you are complaining. So just don't.
3) No one cares
This feeds into point 1. Everyone has their own problems, so don't waste their time, or yours. Commit to a course of action and pursue it.
B. Never explain
This is especially relevant for dealing with women. A beta, who sees a women as superior to himself or as something to be worshiped, will constantly attempt to justify himself by explaining his actions. You do not need to earn any woman's approval, so do not explain.
1) Explaining puts the women in control
By explaining your actions to a women, you are telling her that you need her approval over your life choices. This gives her not one, but two means of control over you: her approval, and by extension, her sex. First, remember that you never NEED sex. And even if you did, which you don't, there are millions of other women to get it from, so you sure as hell don't need her. Neither do you need the approval of some fickle, emotionally-driven, immature being. Retain your control over the situation. Don't explain.
Got a date this week? Show up at least 5 minutes late (feel free to show as late as you think you can without her leaving), then offer no explanation whatsoever. Because you don't need to explain yourself to her. She will conform herself to your confidence and self-assurance and see you as "high-value" because you have a IDGAF attitude. That is the key.
Did she text you last night? Don't respond for a unusually long time (this will vary based on the nature of the conversation) then offer no explanation. At the "worst," she'll flip out and back off from you. This almost NEVER happens. Even if it does, she'll respect you. What will probably happen is that she will interpret your delay as being due to another woman or because she simply isn't valuable enough to you. Her response will be to "compete" by doing more to improve your opinion of her. Profit.
Of course, there are exceptions to this rule, but they are rare. Use your common sense.
TL;DR: Never complain; never explain.
