Don’t worry Newqy, all players lose first, your losses are not too bad, plenty of time to improve.
You start to get even, just by being value heavy, betting good hand, folding bad ones. Remember to have tight opening ranges, and tight calling ranges.
Second step is to start folding even good
hands , when you think you are mostly beat.
Third step is guessing what the opponent has given his profile, if he is wild you play differently, if he is nit you play against that style. At this point you are dominating your level. Remember to make notes, this is the key for 3rd step.
For adaption people like Mikesiance777 is happy to give you his whole stack with over pair when you hit your set, that is the way for domination in third step, but not all players are like that. For domination you need to know who is who.
