I came across the post Mindful Eating which has a great quote:

And when you chew, chew only the carrot, not your projects or your ideas. You are capable of living in the present moment, in the here and the now. It is simple, but you need some training to just enjoy the piece of carrot. This is a miracle.
Thich Nhat Hanh

This is the same way of thinking as in The 5-minute Meditator, a book about ‘spot meditations’. Living in the present makes life calmer.
