If you love something, you would invest in it to ensure its long term survival. The problem is, when you don’t see the future potential, and you are stuck in a conservative way of thinking, it can be hard to want to invest.
My argument is to not think too much in terms of money lost, but in future love gained. Invest in something for the sake of loving it, and believing in it. Not doing so means you simply don’t truly love it.
