How to be more considerate

Hi, I’m in a really great relationship but my partner says that I need to be more considerate of her. I don’t try to only think of myself but it is difficult for me to embody being a more relationship oriented person. This is my first long-term relationship and this feels difficult for me but I love my partner and I want her to feel appreciated.

I hate the stereotype that we’re selfish but has anyone else had this problem? Any advice from fellow rams on how to be a more considerate partner??
