My Personal experience tells me that Money alone doesn't bring you happiness.

Around two years ago, I was working at a middle tier SW outsourcing company, which payed me a respectable salary. Nothing great but it was quite enough for me.

Then I landed a job at a hot startup, which had already raised its first round. They offered me nearly double the salary that I was getting then. I didn't think twice and accepted the offer.

Two years have gone by and all the extra money that I have made in that time has not brought much change in me or my life. I have started spending more freely, but that doesn't make me much happier than I previously was. Maybe it's just me, but money doesn't seem to do it for me!
