SIX PRINCIPLES OF LIFE......
1· No point using limited life to chase unlimited money.
2· No point earning so much money we cannot live to spend it.
3· Money is not ours until we spend it.
4· When we are young, we neglect our health to chase wealth; later, we use our wealth to buy back our health. Can we? Difference is that, it is too late.
5· How happy a man is, is not how much he has, but how little he needs.
6· No point working so hard to provide for the people we have no time to spend with.
Money is no doubt required for a nutritious, well-balanced diet, clothing according to the season, a reasonable dwelling place, needs of the family like health and education and for fulfilling social obligations. But how much do we really need for all these? 
Let us understand the limitations of money..... 
1. Money can buy delicious food, but not an appetite to really enjoy it
2. Money can buy expensive beds, but not sleep.
3. Money can buy expensive medicines, but not health.
4. Money can buy blood, but not life.
5. Money can buy clock, but not time.
6. Money can buy books, but not wisdom.
7. Money can buy weapons, but not valour.

8. Money can buy position in the society, but not respect.
9. Money can buy sycophants, but not true friends
10. Money can attract opportunists, but not well-wishers.
11. Money can buy a house, but not home, where there is love and warmth.
12. Money can buy objects of pleasure, but not happiness.
13. Money can buy sex, but not love.

14. Money can buy make-up items which can break-up, but not beauty. A smile is the best make-up and makes a face beautiful, but money can't buy smile. It is an expression of contentment and inner happiness.
 
Remember -- We come into this world with nothing, we leave this world with nothing!
The things we carry with us after we drop our body are our karma-s (actions) and our adhyaatmik saadhanaa (spiritual practices).
So we need to accumulate more and more of these which we will eventually carry after dropping the body.   
This is the proof that you don't have to have money to be happy!!
