How can I practice loving myself?

Hi! I have just realized that I have been buffering with unsuitable men so much because I am ultimately trying to feel loved. Of course they do a terrible job at it, because I am the only one who can make me feel loved for real. So I have decided to stay single until I love myself enough not to need someone else to do it. Do you have any advice on how I can practice loving myself and becoming stronger at it ? Thanks!
