How do I get women to notice me and not be constantly rejected?

I'm a 45yr old single virigin, who has never been able to find anyone to date my entire life. I'm tired of the constant rejection and would like some ongoing help from women on how to start getting noticed. I'm ok with an ongoing conversation to help with gaining some self esteem and confidence, which I never had.
