This thread is an interesting read, anyway I'm adding in some advice that hasn't already been mentioned, relevant for women in their twenties and thirties (I think):
Be curious about life and the world around you.
Learn how to cook and try all different cuisines. Challenge yourself buy a cook book and cook every single dish in the book.
Save, save, save.
Learn how to swim - it's an important life skill and you'll be able to enjoy water related experiences without any fear, such as scuba diving etc.
Don't be afraid to do things on your own such as going to a restaurant, theatre, cinema, weekends away & holiday's abroad.
Let go of toxic relationship's (male & female).
Don't be a sheep & follow people, know your own mind.
Live your life with the intent to experience joyful moment's every day.
Invest time & money in self care: have regular massages, go to the dentist look after your teeth, go to the chiropodist for foot & toenail care, look after your skin and follow a skincare regime (I favour the Korean type regime with lots of serums & gentle exfoliation) moisturise your body every day.
Keep a journal and build into your daily routine, to reflect on your day.
Have lots of hobbies, do short courses to try different things.
Don't be afraid to try a different career if your current career is no longer fulfilling.
Have as much sex as you want, with who you want, when you want to and make sure you ENJOY sex. Don't continue to have sex with someone that isn't making sure you're needs are being met. Don't discuss or seek approval of your sex life with your friends.
