How could I say that? Not ready? But he's 29! She's never going to get dates if she's over 25!
I meant it. It's better to take a year off from dating and really work on being who you are than to keep dating without being your own person. It is a futile attempt to try to find the one for you when you don't know you.

Arts & crafts
Cooking & Baking
Model train sets
Now granted one of these activities might just be someone's daily workout, and one might be your day job. The point is to have fun and be yourself.
