Hi, should I change my perspective on people? Here's my situation..?

I always find myself to be the guy who's looking to chat with friends, etc.. and make new ones, whether at school or in outside activities. But I find it rare that people have sought me out to genuinely see how I'm doing or ask to meet up to hang out. I find this happened in the workplace too (I'm currently in between jobs). I feel a bit tired of searching people out and saying "hey want to do this or that - hit a pub, etc.." since I find myself the one who asks this often. I have seen some 'friends' answer back with a certain "I guess..sure" answer (they don't reply with an uplifting tone). And sometimes some people don't even reply back or I have to contact them multiple times (email, telephone) before they confirm. So, yeah it does look kind of sad. Actually, not even kind of. My question thus is: should I stop 'taking the initiative' and see, next time, if my 'friends' or 'colleagues' call the first shot in regard to making plans to get together? I don't want to be anti-social, especially now, since as a job hunter, I hear from career coaches that networking is the number way to land a position these days. But at the same time, I don't want to feel that I'm this annoying friend of someone's. I don't want to be that guy who when one picks up the phone or reads his email, the person is thinking 'oh man, not him... ". I think this observation is triggering the idea in my head to consider looking for new buddies. I look forward to your input.
