I eat a very healthy breakfast, and an even healthier lunch.
I also eat veggies and fruits, drink matcha tea with very watery skimmed milk and only one cup of coffee per day. However, on my way back home in the evenings, invariably, a sense of doom descends upon me. Why am I here, what am I doing with my life, am i really happy, should i start over, etc.
Then I come home and eat cake. Copious amounts of cake. And in fact, it does make everything better.
