I gave up coffee for four days because I was convinced there would be huge benefits. Instead my life just got more boring and difficult. Each morning felt like it was on half powered batteries. My sleep was no better or worse. Abstinence Shmabstinence.
It got me thinking though – for creativity and good work to happen, energy is the number one component that needs to be checked off. Don’t try and write a novel on a half empty stomach, or record an album on 3 hours sleep. Go to the gym or for a walk. Being energetic in other areas will probably flow over into your work too. That’s my theory anyways – take it or leave it 🙂
And in case you were wondering, from my limited experience coffee is a very good thing. Don’t deny yourself the good things.
