The 3:3 Method
Make sure your laptop is fully charged going into your work day. Set three work goals every morning. Complete your #1 goal before your laptop runs out of battery. Take a break and recharge (your laptop and yourself). Repeat for the next two tasks. If you finish early, leave early.
It’s just something I do that’s extremely effective for me. Doesn’t require a fancy name, but it does help to remember it.
