Are you an early bird or a night owl?
Me? I am trying to be an early bird these days;)
For the early birds, some early blooming flowers (the purple-pink Morning Glory) and the chirps of robin, wren and blackbird - usually the first to sing. Also a cup of morning tea to revive and why not some candlelight for the quiet time.
For the night owls, some flowers that begin to bloom in the evening (Four o'clocks, Evening Primrose and Moon Flower), the presence of candlelight. Hot chocolate with marshmallow helps too.
