How do I play? NLTRN

[RFitz23]

FYI...I have recently moved up limits due to my win in a MTT of the Nightly 100 grand. Upon moving up you can see I lost a few 500 hus and 200 Hu. Sample size is very small probably around 30 on these, so means little. I know I can play these limtis, however I know I need to refine my game some to be serious playing this limits for obvious reasons. Just want to get some quick thoughts as to what I could do to achieve my highest ROI. I have been playing 1/2 nd 2/4 nl as I feel very soft, only this week(made like 3k). However, I have invested as you can see a substantial amount of time in HU and will continue to play(just a breif hiatus). Appreciate the recommendations/critiques.
