Never underestimate how much energy you can find when you genuinely love the work. The time you spend working on your passion project will pass very differently compared to the time spent on endeavors that don't inspire you.
Our perception of time changes according to mindset and environmental conditions. "Time flies when you're having fun" is more than just an idiom, its a description of an observable quantum experience. Love and euphoria hack the matrix.
We never know how resilient and relentless we can really be until joy is factored into the workload. Don't judge your work ethic by how you perform in less than desirable environments, Judge it by how you vibe in your flow state.
