But then, in order to make use of the thing, you must also pay a second price. This is the effort and initiative required to gain its benefits, and it can be much higher than the first price.

This is such a clear and important point! I’ve never seen it put in just this way, but it will be forever how I talk about the true costs of things, experiences and opportunities. There’s what feels like a variation of Occam’s Razor here too: Even if you understand the second price, don’t buy things, (through payment of money, time, or allocation of storage space,) unless you are also ready and able to make the second payments. If not, leave those opportunities for someone else.
