Earn your own money and keep it in your own bank account.
Think about the kind of life you want, and put yourself in a position to have it. Don’t rely on someone else to provide it- if it comes from them, they can take it away.
Choose partner who is prepared to work as hard as you on your life and your relationship.
Make your peace with ageing and find a way to turn it into a positive thing. Don’t try and stay 25 forever or allow yourself to give up on life.
Set high standards for yourself, and respect yourself for prioritising them.
Don’t expect other people to care more about you than you do.
Don’t run away from problems. Confront them, deal with them, and be proud that you’ve done that.
Don’t use your family as an excuse to abdicate from the rest of life.
