Ego in professional life can hamper your system... :( and ur professional family(Project Members)

Great philosophers and thinkers have said that what we see is the one which we want to see or the way we take in. And for this, they explained it giving an apt of our eye lens... They figured out that when a human with a dithered vision sees anything. Then all the surrounding will seem to him in a same dithered manner. But human do not blame the world because he knows the things are not in the way he is taking. So he tries to modify his vision with the right lens to have the correct perception of things.
But this has introduced one more doubt in my mind. Do the things we see surrounding ourselves are the same. We have defined various colors... red, blue, green etc... But are they of the same color. I mean, we see an object as red, but is it really red or of any other color. When we see an object, we measures it to a certain size x. But it can be that the object measures more or less than x. Till the rays reach our eyes, it may change. Oh no... But our ray’s theory says that rays travel straight and many physicists have proved it. But what they have assumed for the theory, what we have assumed for the theory acceptation IS TRUE? All this things are made by us. Everything is defined by us. We are creating our world as per our perception. But is the world really like this. Or are there any hidden secrets which are still unknown to us. I may be wrong. But it is true, we don't have any proof. As my colleague said, it is all that we accept from what majority of our human class says. We can't prove it.....
Finally its all maya...and we are living in the fake world...we are yet to see the real world...
