I see a lot of excuses in the thread why not to have a child (including age). Septimus Sever had first child after he was 40 years old, his first wife died childless and he saw a lot of violence and risked his own life many times before finally had some.
The thing about children is that they bring this incredibly powerful amount of purpose in your life. You look at your kid and suddenly you realise that some things have more sense than before. They also bring hope that all your work and material possessions you acquire may serve greater good in form of your descendants and their actions.
However children demand attention, energy and financial resources to grow properly - this also requires having a proper partner.
The best person for that is the person that matches your values (qualification just by SMV is a mistake) as you need to be able to transfer your knowledge and values to your children unopposed in this respect if your character has more virtues than vices - and another person with high values will help you with that (btw. my wife would never allow herself to be in any 'rotation' of lousy PUAs and that is what I will teach my girl as well
)
Anyway, being 35-45 is a perfect age to finally properly qualify a woman you want to have children with - if you had them before, there is a chance that looks of your partner overshadowed deficiencies in her character (which also means they may be later passed to your children).
But having children requires being of character - you need to be giving, rather than demanding (but you will still need to demand proper behaviour), you need to be compassionate and patient a lot of times rather than short-tempered and uncaring. You need to have a logistician and strategist in yourself. You need to leave your egoism behind and also drop the idea that acquiring material possessions and experiences are the most important things -- nevertheless, you still need to acquire them for sake of your family. You need to be able to lead by example.
Therefore you really need to want to have children before having them and all the lures of having comfy life of 40+ childless player are strong (which is ok as it's quite Darwinian - people that possess qualities to bear children usually have them - even if those qualities are poorly developed/basic - most of the guys that have their first child in early 20's are examples of passing the most popular qualification for bearing children which is high sexual interest in their current female partner and having constant sexual access to her - this in spite of their experience, resources or virtues of character).
