Do you think that Money really is the key to happiness?

No, not at all.

Happiness comes from inside, it is not affected by outside forces, money included.

*BUT*

More money == more time and opportunities to pursue things you love, and help people around you, and that is pretty dang nice.
In the end, money is a multiplier; it gives you more of who and what you already are. =)

I have written quite a bit on the subject of money:
