If you've been having trouble with making things happen the way you want them to in the game of love, it may be time to reassess your strategy. Tactics you used to use -- even ones that were successful in the past -- are no longer working. Maybe the person that you are inside has changed, or maybe everyone around you is different; but something in your methods is now obsolete.
If you used to rely on your looks to attract admirers, that may not work anymore, at least not for long; physical attraction is only the first stage of drawing someone your way. You have to have the personality, kindness and energy to back it up. And you do have the personality, so why not play it up? Instead of bragging, clinging or whatever other behavior inspired by nervousness that you revert to when you're out on a date or chatting up someone cute at a party, try just being yourself. This can be difficult, especially if you have a deep-rooted sense that you're not attractive enough without some kind of embroidery (like being really hot, or bragging, or clinging...). But you'll find that you get a much better reaction when you're relaxed and authentic, with nothing to prove.
