losing streak. how do y’all do it ?

haven’t had a win in a while, even though i crunch numbers. what am i doing wrong ? what methods do you guys use ? i usually bet on points, and find the average of any given players last 10 games. should i stop ? give me some pointers plz. dont wanna zero out cuz i promised myself only a one time payment and to call it quits after that. anymore is chasing the dragon imo
