Yea, get a feel for the table...usually "life is a long session" outlook applies but if you notice that you're losing session after session at the start, it might be a mental leak trying to exert dominance or a bully, or whatever psychological babble you want to put in there
You could also play some smaller stakes to warm up, like if you're a 100NL play 10NL or something that will get the creative juices flowing
