Widen your circle of opportunity
You're already enhancing your opportunities by treating every chance encounter like a speed date. Now you've got to reconsider your 'circle of opportunity'. Research shows we have a set geographical and emotional 'circle' we operate in - taking the same route to work, going to the same pub after work, always seeing the same friends and doing the same things.
Seeing as your circle of opportunity hasn't brought you the love of your life it needs changing. Start widening it to maximise love-opportunities. Take new routes to work, go to new places, take a selection of evening classes, enlist a friend to try new bars and clubs with you, and check out some of the singles events in your area as well as internet dating.
