Money definitely facilitates a degree of freedom, which I think is what you're really after. Problem is that it's easy to exemplify money as the solution without really thinking about what would truly make you feel fulfilled and free. As the prior poster said, our society is money driven, which obscures our thoughts sometimes. Sure, we might be able to afford therapy, but it might not work.
Don't get me wrong though, money does help. But there is a threshold beyond which additional money doesn't matter. I wouldn't say extreme wealth is necessary to bring about the opportunities that make life fulfilling. But some wealth (and spare time) is definitely needed.
I mostly speak from what I've seen in other people. I've known people who have never worked a day in their lives due to generational wealth. Although they have the ability to just go on holiday whenever, they're extremely depressed, because they have no accomplishments that they can call their own. Physical ailments which can't be easily cured also plague them.
Another example is of someone who horded wealth their entire life since they liked to see their money pile grow. But they died miserable, since they chased everyone away out of fear of those around them stealing their money. In the end, they died never spending anything.
Just figured I'd give some examples, since life is anything but straightforward. But hey, if you have a clear plan of what you'd do with the money and are certain it'd be fulfilling, then it could go a long way.
