1 & 2 are different for everyone. I get an energy boost from working a certain amount of really productive hours during the week. Be self-aware, meditate, and identify the symptoms leading up to burnout. Err on the side of caution when it comes to preventing exhaustion, but let yourself binge on productivity if you're excited about the work you're doing. After you're done with that project, if you have a chance, take some time off and do something completely different. Surround yourself with people, opportunities and environments that make you excited to take a break.
