How can i begin to try to improve my relationship with my only living parent whom I seldom get along with?

hello, i am not sure if i should be posting this inquiry in either the family, friend's and relationships section or the psychology one since my issue is a bit of a overlapping problem in both those categories thus, i ask of you to please in answering do not tell me to just ask this in another category, thank you!. ok, here's my issue: i have one living parent whom i don't get along with i predict 362-363 days out of 365 days of each year, we are both very different people--my mother and I, we have no parallel hobbies, sports, interests between us and our personality's likewise are very diverse as well. I am unconventional, liberal, genuine, artistic and free spirited definitely a person who makes decisions with my 'heart over my head' for sure and she (my mom) cannot be more opposite from me than night and day are, we disagree about everything since we comprehend of things going on in the world in different lenses--we fight constantly, about the littlest to the largest matters. its really upsetting because when we do talk (which is seldom once a week sometimes once every 2 weeks) it seems as though in conversing one of us is just trying to prove the other wrong, put the other one down or end with a firm affirmation of uncompromising beliefs, opinions and viewpoints. so, as you can ume; we have a very dysfunctional relationship. we have nothing to talk about that we don't end up fighting about since we both have different opinions on just about everything. how can i make our relationship a better one with less anger and ugliness? i really don't want to believe that it is too late for us to find some common ground to talk about and occasionally smile over? please be as specific as possible if you can on subjects we could talk about, things we could do--little or big every-now-and-then for one another to show that i do and that she does still care for me despite our abundance of differences.
