Archibald Marwizi said this quote
“ Work is simply, “force x distance” or the product of a force applied to an object and the displacement of the object in the direction of the applied force…holding an object in the air does not involve any work, no matter how painful your hand will be after a few minutes… reflect on your daily activities and the results from them. Are you really working or just increasing your potential without progress or desired results? Your work must produce some movement, progress and change, by effectively using all your energies whether intellectual or physical. ”
