Something that ive noticed happens far too often us that people compliment others while bringing themselves down. For example you look soo good why can't u look like you. Or, you look amazing I wish I looked like you. , you have the dream body/ body goals. I mean it's great that you are complimenting someone else, because we need more of that. Compliments, however you don't need to bring yourself down while complimenting others. Tell someone that they look good without saying you wish you looked like them.... Because you are YOU. You will never look like someone else and you don't need to either. You need to learn to accept yourself and be happy in your own body. But also learn to compliment people for other reasons than their body. .... Because I can tell you, being told I am smart, funny, clever, a great baker, I am strong, a fast runner etc are much better than being told I have a nice stomach or am "body goals". . I am more than my body. But also those compliments are so appearance based and not about the actual person or what they are good at etc
It can also be important to learn to compliment others because you want to make someone else happy and you don't expect a compliment in return. But also give honest compliments, the worst thing I know is fake compliments..... Learn to give more frequent, honest compliments without saying something negative about yourself.
