It’s a good idea to regular breaks.
Every break will help you clear your head, and ultimately increase your odds of success.
“Break” means a change of scenery.
Unfamiliar surrounds (and people) allows your brain to change gears.
You don’t need to go to Sicily for a change of scenery.
Go down the road to a guest house.
Or drive 2hrs into the bush.
Or 3hrs up the coast.
Three days in different scenery is all you need.
