I think the problem is in your question - you said no girls approached you. See, it is not their job to approach you. By definition, a man is someone confident to pave the way and not fear rejection. Does it mean you will not be rejected? Of course not; you will be rejected many times, and there will be times when it will be you who will back out; that's the way of life. Rejection is not a failure, it's just part of the process, you will not get every job you are interviewed for but still you will apply and try as many time as required to succeed. You need to build self-confidence, work on self-improvement, and stop putting so much value on success; you need to enjoy meeting people and building connections.
