Don't try to gain joy just by changing the'environment.' Instead, gain joy by always changing the 'heart.'
If you want to gain joy from the environment or only things you see with your eyes, you can't gain it every day and often.
Therefore, change your 'heart,' and gain joy from the heart.
By changing your heart appropriately, find and gain the joy and gladness from the heart.
A human beings live with the brain and body.
Environment is something you make in the brain while thinking.
