Ok yeah at some point i am probably gonna get tired of being single but for now here's why I love it:
1) You can flirt with whoever whenever guilt free. As long as you don't lead them on too much, you don't have any commitments to anyone so you're not obligated to hang back.
2) You don't have the pressure of keeping a relationship going. And this is not to say relationships are terrible and to hard I just feel very free when I'm not in a relationship.
3) You have more time to think about you and spend some "me" time. As much fun as it can be in a relationship sometimes you can forget to think about you and just do what you want.
