adjusting plans is better than without plans

ya, yet another instance of the merits of dreaming or imagination.
you won't be able to get it if you don't dream for it, by the way, imagination and visualization of what you want to achive does help to the realization of it.

There is one intersting experiment in which the olympic athletes are asked to imagine that they are in the track and run, surprisingly the devices hooked to their bodies show that their muscles fired just as like they are competing in the field. This tells that if you think about it, if you dream about it, you can get it.
