How do you manage your stamina?

I'm playing orochi as my main and have only recently come back to the game after a long pause, trying to get back into it. My main issue is when launching offense, I often find myself out of stamina, and it seems most of the time even if the enemy fails to block, all if my stamina isn't enough to kill.

I'm looking for ways to think about my stamina more efficiently, have any of you got a system in place to better think about it without it costing too much of your attention span?
