I am here to add life to Life. So I will give you a piece of advise:
You only need five things in your life so as to be happy:
1. Health. Without health, you cannot take pleasure in existing.
2. Good environment. A good place to live and to explore.
3. Something meaningful you love to do.
4. Good companions, people to share love and laughs with.
5. Something to look forward to.
Remember to save money for your future and you will be your best friend in old age.
