I've had the same quandary as you for the past seven years or so since beginning working on the global energy problem.
I knew nobody would pay me to do it, but I do it anyway.
Even until now when there is an official question over my sanity.
And guess what, even if it doesn't make any difference to anyone, I still feel much better than I know I would have done if I had done nothing.
I could die happy knowing this.
But I won't give up fighting until I draw my last breath, because I know we will win this, even if I don't get to see it, the good force of life and creation will win this, because it has truth, and the path of least resistance.
I know also that I had to make the positive effort to understand the positive rewards of it, money already means not a lot, it's a necessary means to an end, we just use it wrong, by monetising destruction instead of creation.
The instant we move to solar indexed stimulus, we will never worry about money again, and if you and or I live to see it, we will have all the funds we ever needed to do all those things we wished we could do but never did, due to lack of time and or money.
I think if we know we contributed to achieving it, we'll be much happier when it happens.
There we might see the benefits of faith, vs no faith.
