just to be clear this is not for a competition but rather just an intense large block of working time, correct? In that case my recommendations are: - have your supplies stocked and ready before hand. You dont want to have to think about what you'll drink or eat or listen to. - you will need breaks so the key is to make them meaningful. (either productive or recharging) You can either go walk outside for 10 minutes, do some form of exercise for 5 minutes, watch a quick video of a code tutorial or other relevant content, etc. - Plan what you're going to work on. Having an outline of the things you're going to accomplish and the order in which you'll tackle them removes a lot of guess work helps keep you productive. - Get a buddy. For most everyone, having a partner (even if they're working on something else) will help keep you focused.
