Drive it. Charge it. Repeat. Vary how much you run the battery down, occasionally running it down as far as you can while still making it home or to a charging station. It's made to be charged up and driven. Don't over think it. It doesn't care.

Prior to model year '14, where Nissan removed the charge to 80% option, they had all sorts of warning in the owner's manual about high states of charges. You can d/l a copy from https://owners.nissanusa.com/nowners/na ... nualsGuide.

I pointed to examples of that from page EV-24 of the '13 manual at viewtopic.php?p=498123#p498123.

There's also literature (unfortunately, not for the li-ion variant used by the Leaf) that suggests that it's worse for li-ion batteries to be kept at higher states of charge, esp. at higher temps. Examples:

'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
'06 Prius

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.
