There are days where you’ll be feeling really tired, and won’t want to keep doing anything.
That’s fine. Everyone has such days.
It does not mean you’re stopping, it just means you need a break. Take the time to rest, to get better. It’s your body’s way of telling you that you should take it easy for a bit.
This time is as important as the time you get down to work. Make the most of it by also letting go and relaxing, to come back refreshed and with new ideas.
