I really like this topic. I guess the short answer is that you should work on achieving inner happiness while also working hard on becoming rich, especially while you are still young.
I’m not a Buddhist but the teaching of Buddhism is great, it gives a lot of understanding of humans through understanding of self. I don’t consider Buddhism as a religion; in my opinion it is much closer to science than to religion.
The inner happiness is something like a natural state of a person. In western society, “normal” person gets “happy” when he achieves or accomplishes something – when he gets his diploma, wins some competition, makes great salary, buys luxury car, gets this hot girl(s)… The problem with this happiness is that it is goal oriented. You must get X to be happy, but once you get X the happiness is gone, and now you have to seek Y to keep happy. Once you get Y you will have to seek X to remain happy. You are never happy NOW, you are always moving the happiness to the future – only after you get X, Y or Z you will become happy. In western society there is always this great DESIRE to achieve X.
So you have to work hard to get X. But what if you can’t get the X? The great salary and position, hot woman, great vacations? What if you fail the competition for which you practiced for so long? You will feel miserable. You failed your dream of being happy. Your DESIRE will eventually cause you MISERY.
Example: Many people are still chasing the American dream. You work hard, you save money, you become expert in your field – and eventually, perhaps after many years of hard work, you will get rewarded- you become independent and rich. But this doesn’t really work anymore, there is only small number of people who reach this American dream. Other people also work very hard but they can’t get ahead of themselves, they lost house because of bad economy, their business is being destroyed by reckless ruling and enormous taxes… They keep Chasing this dream but they can’t really reach it, and it causes a lot of depression and frustration, a lot of misery…. There are a lot of pissed people out there, they want to work hard and get ahead but they really can’t… Their desire to reach the American dream makes them miserable…
Same with girls – if your desire is to seduce lots of girls but you are failing for some reason, you will be in misery.
So Buddhism teaches about this suffering, it teaches to be happy without any attachment. It teaches that you should drop this DESIRE to avoid misery, and once you drop it you will become naturally happy. You are happy NOW, and you don't need anything or anybody to be more happy. Which makes sense and is also true...
You can be happy without being rich or having great position. You can be happy without girls, you can be happy without education. You are just happy because you simply don’t desire those things, there is nothing or no one to Chase, there is nothing to win, there is nothing to achieve or compete against. There is no desire to achieve anything, accomplish anything, to be somebody…. All there is is happiness…
Ok, but this kind of happiness is a BS too. We all like nice houses with air conditioning and heater, we all like nice cars so we can get around, we all like girls. If nothing else, we all enjoy flushing toilet with toilet paper instead of living in the caves and wiping our asses with leaves…
So the happiness should be something in between – you want to get money because money is freedom and comfort. You might want to get some decent place that you call home, just so you can invite girls there or use that flushing toilet there. You might want to get reliable car so you don’t have to waste your time somewhere on highway in rain or snow. On the other hand, how much comfort and money do you really need? How many girls do you really need to seduce to be happy...??? You should learn to be happy without money and without girls… And once you became this happy you will actually find out that it is very attractive to girls - you don't chase, you are not clinging, you don't get anxious, you don't suffer rejections... and girls feel it, they want to be part of it...
So yes, having money is great, but do you really want to break your back because of that? I broke my back by working very hard in the past 10 years or so, I get decent money and I will most likely be making much more. I reached the American dream, relatively speaking, I even reached further than I ever dreamt of. But at the end I am always asking – was it really worth it? Was the hard work worth it? I always say yes, but there are real doubts on my mind…
