Be positive. Life is beautiful and positive attracts positive, so to make sure you are getting a great date, just be great yourself!
Talk with, not at. Listening and questioning are a very important part of every conversation. So, if you like your date, show your interest by listening and asking questions.
Flirt but just not too much. Flirting is great, but can also give the wrong impression so better not to over do it. There'll be plenty of time for flirtation when the relationship develops!
Dress to impress, smart/sexy but without looking like you've tried too hard. Moderation is everything. Be clean and well-groomed, and dress appropriately for the occasion - casual for the pub or local restaurant, smarter for the ballet or theatre.
Beware the demon drink. When you're excited and maybe slightly nervous, it's easy to keep on refilling your glass. But you want to keep in control of yourself, so how about limiting yourself to just a couple of drinks. And a woman particularly might question the motives of a man who keeps trying to ply her with alcohol...
Just enjoy yourself. Meeting new people is fascinating, especially when you may be meeting your future partner, so it helps to feel optimistic and look forward to having a great time together!
It's your turn to be happy! So good luck and have fun!
