You really have to be the best you can be, for yourself, even BEFORE you meet the guy.
I know it sounds weird, but please believe me on this one.
If you are satisfied with yourself and what you have to offer, it won’t feel like you HAVE to IMPRESS someone—- that thought won’t even come into your mind. You’ll just be you, and it will come naturally.
Be happy – happiness comes from within. Love yourself fully. When you love yourself and accept yourself, it shows.
Education is enlightenment. Be smart. Learn more. Shoot for the stars. Know what you are talking about and back it up.
Be a person of utmost integrity. Speak with confidence and grace.
Once you have fully evolved as a person, you won’t feel the need to impress others. Instead, others are going to want to impress YOU. I hope this helps.
It also depends on the man you are interested in. His age, his personality, his interests, etc.
Good luck and remember—Let things flow naturally, be yourself, and don’t worry too much about what he might think. Just focus on yourself and allow yourself to reach your full potential as a human being and woman.
