Yes, there are so many book around the topic of self-love, that focus solely on the form of how to show yourself this love. It's not the symbol, but much more the content of your mind/heart that makes the difference. If you buy someone flowers out of guilt or a bad conscience you haven't done it out of love - same if you do it for yourself.
I guess this is because people are so focused on form and not content, that they believe love is in the symbols. ❤️
