Actual focus, where I am 100% on the problem with all my remaining grey matter? 3-4h. That doesn’t mean I am doing nothing the other time - I’m talking to people, thinking about stuff, setting stuff up and so on. But if I do more than 3, 4 h, quality suffers, I suffer, and my sleep schedule suffers.
Depending on how you land, you might be quite limited in positions anyway
