How to Actually Lower Your Standards?

Hi everyone. I was hoping someone would be able to give me some advice about a problem I have. Basically, I find it really hard to find people I'm attracted to. And when I do, they don't feel the same way. As a result I've been single for a very long time. Basically, it seems like I'm attracted to people out of my league, and I need to lower my standards. I was wondering if anyone has any ideas on *how* you can actually do that?

The big problem with the 'lower your standards' advice is that you need to be attracted to someone in order to have a romantic relationship with them. I don't see how dating people you are not attracted to is an option – you need to find someone attractive to fall in love with them. So the question I'm asking is if there is any way you can get yourself to find more people attractive? The only thing I can think of is to stop using pornography, which I think unconsciously raises your standards of physical beauty. But I've already done that, and haven't used it for a year or two.

In terms of the kind of people I find attractive, I think there are four main things: Someone being a nice person, Someone having similar values and interests, someone I find attractive physically, and something else that it's hard to put your finger on: something about their manner and their way of carrying themselves that you find attractive (maybe you can call that 'chemistry').

Any advice would be much appreciated.
