Do you find yourself working hard so that you can deserve some time to rest? That sounds very normal, but its actually a trick question. You should never be working hard so that you earn rest.
Rest is not a reward. Rest is a need!
You wouldn’t deprive yourself of food or sleep because you haven’t earned it. (Okay, well you might, but you can realistically look at that and say you can’t keep that up for long!)
Same with resting. You need nourishment, inspiration, enjoyment, rest, relaxation, and breaks. If you don’t take time to rest you can’t be productive when you're supposed to be, and you can’t put your heart and mind into your work because you just don’t have it in you. You are exhausted and depleted.
Sure, you can push yourself for a while, but eventually you will break down. Just like your body stops running without food, your inspiration and creativity will crash and die without proper nourishment.
So if you think you don’t deserve to rest. You are sadly mistaken and doing yourself a disservice. When you give yourself permission to rest, then you will have what you need in order to move your goals forward.
