How to maintain confidence in dating?

This may be an age old question, sorry if it’s a repeat one as well.

I just want to know the best way to maintain confidence in the dating scene. Self confidence at least.

Don’t get me wrong I’m not taking these rejections to heart, just you know it still doesn’t feel good getting more rejections to wins(couldn’t think of a better word).

I’ve just seen a slight drop in my confidence levels and could use some advice on making sure it doesn’t happen again.

Thank you all in advance, and let me know if further clarification is needed!!
