How does working all the time affect ones attitude and mentality?

Manual labour is more healthier than mental labour for the reason, manual labour keeps the body healthy and therefore the mind becomes automatically healthy. Mental labour makes the body sedentary in habits and therefore unhealthy and in unhealthy body resides an unhealthy and unhappy mind. Secondly, in all manual labour there is an element of mental labour whereas in mental labour there need not be any element of manual labour. A harmonious equilibrium or balance between the two is ideal body, mind and spirit..
