Asking is a strong way of pursuing things. If you are able to ask yourself and others like you then you are doing it right. Don't be afraid of those who think that this is impossible. Ask yourself how to avoid thinking that it is impossible as a first step to make it possible.

Maybe. In a very small number of cases. Most of the time it is people either a) struggling to come up with ideas or b) trying to figure out a way to solve their dream with minimum effort.

It's not technically impossible. But setting out to make $1Million in 3 years is generally a non-optimal approach.
I'm a realist in the sense that I figured out a long time ago that truly impossible goals are worthless and, generally, counter productive. Here's an example of how to fix that; one of my long term goals is to go into Space. This is technically feasible now, but to do it I'd need a few million $'s - so that's a good hack, I can work to achieve my goal through some means and the money should be incidental to that. But it is not limiting because I may find another way to achieve this goal without the cost.
