Are you aware that you can become so obsessed about finding a girlfriend that it can backfire on you?
You can get so preoccupied with the concept of finding someone special to change the way you feel about yourself in a positive way. If this is the way you feel, then you may have an underlying problem with your self-image. That being the case, work on yourself instead of trying to find a relationship with single women that will miraculously heal your self-image.
One thing that can really hurt you in your pursuit of single women is trying too hard. When you try too hard you tend to come across as desperate, overly anxious to get involved with someone, appear depressed, etc.
This can really scare women away when you try too hard. You will do much better when you feel relaxed and self-confident when meeting and approaching single women.
So, in closing, it's best not to become overly obsessed in finding someone to love. Another drawback to this mentality is you will tend to lose interest in other important areas of your life. Your friendships may suffer, you may stop enjoying your hobbies, become reclusive, depressed, give up your recreational activities, etc. You need to live a well-rounded life filled with lots of social activities, sports, reading, meditation, vacations, etc. and not spend all your time getting depressed because you don't have someone special in your life. Be patient, my friend, and before you know it, you can meet the love of your life.
