I try to make it pretty balanced. Dnd isn't really balanced around constantly long resting, and I think resource management is part of the fun. Low level spells are pretty meaningless if you always have high level spells slots to blast through and such.

So my approach is this:

1. Only long rest after my 2 short rests
2. Short rest when reasonable, such as when the party has a good chunk of HP missing.
3. Generally aim for 3-4 encounters per long rest (encounters don't have be combat, can be anything you expend resources on, such as healing or charming an NPC)

So far it's worked out pretty nicely. It makes the game more challenging and rewarding, imo.
