I dated a lot of people that didn't work out for me. I even married one. After that, my standards went pretty sky high. I didn't want to be alone, but I wasn't happy with someone that did't fully meet my standards. I bounced around a lot.
I met someone online just last summer. Actually, I'd met four or five before him, but after a lot of trial and error, I found one that had everything I was looking for.
The moral of the story is, you'll likely have to kiss a lot of frogs before you find your prince....and don't be so hard on yourself, you're only 23!! Standards are not bad thing. Unless say, you are asking for something thats a complete imbalance.
I find a lot of people say they have standards, but aren't realistic about them. IE if you're working at McDonald's, it's pretty unlikely you're going to date a lawyer. Or if you weigh 300 lbs and want to date a hot, sporty guy. Mismatched lifestyles. Also, there's a lot of people looking for someone who is the opposite of themselves because they want someone to complete them or fill in their perceived shortcomings. I always said you need to be happy and confident in yourself, complete in yourself, before you are ready to be with someone in a fulfilling relationship. Standards are void if you don't have any for YOURSELF.
Good luck.
