happy#043 – million is just a number

I so much wanted to be a millionaire when I was young. Now that I am, I had to to find out, that I forget to specify the currency. Since then i keep asking myself what the currency means anyway. It is just an agreement build on trust that a million here is more worse than over there. And still, a number can always be taken away from you.
What does it make sense to invest in after all? Maybe time?
Wanna be a time millionaire?
