I come from a heavily Buddhist culture that preaches disconnect from materialism, and I can truly say that it hardly holds. Please LOVE money, because no matter what anyone says, wealth gives you:
1. Independence
2. Confidence
3. Ability to solve problems by throwing money at it. This one's super important as we're heading towards a world where medicine is advancing enough to cure most ailments, even cancer and aids are likely to be cured in the next 30 years with the advent of Gene therapy and genetically customized medicine
4. If you actually have #1,2,3, your chances of finding love are higher, as you can devote some concerted amount of time towards finding love that many poorer folks don't have. Plus confidence & independence are attractive characteristics.
The only thing you should learn to modulate is expectations on how quickly you can accrue wealth. For the 7 billion that are alive today, there are probably a thousand billionaires, tens of thousands with hundreds of millions, a few million with <$10M and the rest are well below $1M in net worth.
So, statically, you're more likely to be in that <$1M net worth bracket, despite your best efforts. Happiness lies in knowing and accepting the likelihood of you ending up in the >$10M net worth bracket. It's low, but happiness can also be found in planning and executing a life towards that goal, while being aware of the low probability of getting there.
So don't give up your "greed" for money, but do give up your unreasonable expectations of getting rich quick. Be pragmatic about how rich you can get (best case, median case, worst case) and plan towards getting there
