There is still a balance, and surely it can be more rational to invest rather than to consume, and some kinds of investments generate income for life and provide security and/or opportunities for improvement and/or advancement.. so frequently guys might not recognize needs to improve their abilities to produce income in their youth or that their ability to produce income in their youth can result in a variety of compounding effects later down the road that further improve their income and/or their quality of life (even though it might cost a lot in the short term).

There surely can be difficulties with bitcoin, and sometimes waiting makes sense and other times waiting does not make sense and we are not always going to realize the amount of the payoff... and there are a decent amount of guys who likely spent too much money on buying themselves a house too soon, and so they ended up missing out on opportunity costs of that money.. I had made some similar mistakes in my youth, yet with bitcoin currently in the picture, the choice could be more grave - and yeah, sometimes a person might need to the security of investing into something like a house - yet other times putting that money in bitcoin would have had been the better choice, even though at the time of the decision it was not very clear in regards to which place to put value is better - which could be the case with your solar panels - even though surely, you are in a better place to engage in the various calculations - and if you are at least attempting to be honest with yourself you might go through various calculations and also see how those calculations play out through time.. not that any of us can go back on some of our earlier decisions, and also there surely is value in some of the subjective value and including value that others are also getting from the thing that you invested into (namely solar panels in your example).
