How much important is it to me? very important, in my humble opinion.
I don´t see it as a black and white matter, there are shades of colours in-between.
If it wasn´t important, we wouldn´t have Economics/Finance and related sciences, with thousands of people studying the subject, and even non-related (think Engineering) ends up dealing with it when they have to erect a building in a more economic way (Civil Eng.) or consumes less energy (hence it spends less
money) - [Eletro-Eletronics/car makers/gadgets etc].
I cited Engineering in a sense, we all know that all fields are intertwined with money-related issues these days.
There are some inventions, that we forget to thank for their existence, like Energy, the press (Gutemberg) and the writting itself, the accounting and the use of the "zero" in it, the iron, the agriculture, the wheel, the lever...and the list goes on and on.
With time we take them for granted, and even forget them, till we are short of them. This is the case with money, just think of the times people were paid in salt, seashells or in the form of barter (bartering services or goods)...
In fact, the world came to a stage in wich money is very very important, along with many other things as well.
Even in simple events, I have to buy a chocolate in this Easter time or in Valentine´s time, then money is important to me, as important as remembering these dates...
One would say, not as important as health, happiness, a kiss, recognition etc, , but as I said above in the Engineering example, one contributes to the other, the intertwined thing.
The answer to the question? very much. It´s very much important, instrumental in getting things, in achieving goals, and vice-versa.
Ah, and you guys feel free to proofread/edit my text. Might have a lot of mistakes, he he.
