For the last couple of weeks , I had been stuck in front of my computer working on a project that was very important to me . My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead , I was feeling rather depressed . I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie,but to no avail. It was only when I turned to meditation(沉思) for a solution that the answer came to me : turn to nature!
The very next day , I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve , even though it was pouring with rain . Within a couple of minutes I felt alive again.To be honest . I felt like a young school girl again and had to stop myself from hopping along the path singing , “I’m singing in the rain.”a song I used to sing when I was a child . I think as adults we often try too hard to control our inner children and as a result we restrain(限制)our own spirits , which only leads to depression and stress.
Interestingly,it has been shown that people who spend 40 minutes walking  in a nature reserve have a drop in their blood pressure levels. But this does not happen when they spend a similar amount of time walking in a busy city centre .
If you feel a little low in spirit and know that you have spent too much time indoors , relax completely , remove your shoes and let your inner child come out and play.
