Dear Bezhad :
Working hard can turn into is a serious disease.
I know it perfectely as a 14 years computer technician !
Making 3D, a drop orange juice, a jump in a nice swimming pool is part of a human life
My advice : take your favourite camera and go for a walk in a field.
No noise & stress, "above us only sky"
Moles, rabbits, cows etc... will tell you that you are on earth for a very short time
...so how about living ?
