The best things in life are definitely free. The best thing in life is happiness.
When I think about what makes me happy it is books, nature, sleep, food, friends, family, smiles, painting, drawing, colouring, singing, and memories but if I have to bring it down to three I would choose art such as painting, drawing, colouring, singing, and books. The next point is nature, sleep and smiles. Last but not least it is friends and family.
So if I do something I like, enjoy nature, and be with the people I love I will be happy.
That is THE BEST thing in life!
