I read it a five years ago. Basic concept is always be humorous, confident and independent. When you see a girl/woman you like speak to them and ask for their number within 10minutes if it's no never speak to them again. Wait a few days text a little light heartedly and then ask them out for a drink so your not over investing. Be humourous and playful try to kiss them, and then after this point you wait for them to message your first 80 percent of the time. Always be playful, humorous and independent, try to sleep with them but never ask for a relationship or act commited and never be too available. Let them bring up being in a relationship and basically repeat this until they bring up marriage and repeat it for the rest of your life. If they break up with you do not contact them until they contact you. If they are overly rude do not be afraid to walk away and if they become distant give them space straight away. Never show jealousy.
This is basically the jist
There are a lot of positives it is good to love freely, to be light hearted, confident and independent. It's also good to be able to give them space and not clingy and message all the time or be jealous. However it is a bit extreme, and is perhaps more applicable for men who just want flings or one night stands. A person isn't going to trust you enough for a meaningful relationship or marriage if you are this aloof, there is a balance. Absolutely be light hearted and independent but also be genuine and open to respecting your partner and there's definitely no harm in messaging every few days or once a week as otherwise they won't trust you. If you have to be this distances for them to keep attracted to you, then it is arguably a very feeble attraction.
This is my honest review it is a good book that teaches you some good lessons especially to love freely, however this should be taken with a pinch of salt and applied with balance. You still have to communicate honestly with your partner. I would apply the positives in balance.
