Engineering - friends = sleep More sleep more moneys

The wrongest equation have ever faced , when we say the most important part of engineering is communication skills. so can you tell me plzzz why do we improve our communication skills? just to get the job? no way the most important part of every thing in life is friends ( relationship) if you failed to have friends so you would be the failure. because study don't make us laugh but friends and their memories do. engineering+friends+sleep = perfect life , and only legends can deal with this formula 😎😎😎😎😎
