I found sleep and exercise are key. I'm not saying you have to go to they gym every day, but find something that works for you. For example, I like to take Saturday off and hike when I can. As for actually getting work done, I find a change in environment is crucial. Even just going to a coffee shop with the intention of only working there is enough to put me in the right head space. Most likely everything is fine. You have funding, you have runway, you have a team. In the long run 90% of your immediate worries won't have an effect. So just find those crucial 10% and go all out on them. :)
