Something simple that can brighten my day is:
1. Bright Sunlinght in the morning, When its sunny I always feel up-lifted.
2. Yoga and Mediatation in the morning.
3. When my both sons are happly with their studies, I feel proud Mom.
4. When my husband is happy with his job performance, I feel proud in society and ofcourse feel more good.
5. When I see comment on my hub.
6. When somebody is following me in HubPages.
There are many other small thing which make me brighten for exampe, When my apricot trees bloom and then there is fruit too. Herbs in the garden and when somebody come to my house and say oh, Your house is so decorative and nice.
