I've only done like 3 approaches, and they haven't been too successful — I haven't really felt a good vibe, so I leave, and in one case an average looking girl was really rude to me, so that's why I've been discouraged. Plus, i've read a lot on this forum that cold approaches usually go nowhere like 99% of the time.

Does cold approaching do anything for your confidence? Is it worth giving it a try?
