Frigate birds are known for their endurance. They can fly for weeks, even months, without stopping.

According to Henri Weimerskirch, an ornithologist who spent years tracking a group of them, frigate birds can fly for such long periods because they take advantage of favorable winds and strong convection, and rely on thermals and wind to fly at very low energy costs.

They soar inside cumulus clouds, using their strong updraft (even though it's freezing).

If what you're doing requires feats of endurance, are there ways you could make it easier for yourself? Have enough reserves so you can run things on the back-burner for a while if you need to. Keep your operating costs low and be as efficient as you can until you have the resources to scale.

You can't do this without taking care of yourself. Getting enough sleep and exercise will make you capable of sustaining the frigate-like endurance you need.
