Much of life is ruined for us by a blanket or shroud of familiarity that descends between us and everything that matters. It dulls our senses and stops us appreciating everything, from the beauty of a sunset to our work and our friends. Children don’t suffer from habit, which is why they get excited by some very key but simple things — like puddles, jumping on the bed, sand, and fresh bread. But we adults get ineluctably spoiled, which is why we seek ever more powerful stimulants, like fame and love.
The trick …. is to recover the powers of appreciation of a child in adulthood, to strip the veil of habit and therefore to start to look upon daily life with a new and more grateful sensitivity.
