The difference between knowledge and love are stark.
You gain knowledge by consciously deciding to read books or going to school or college. BUT you can never gain love by consciously deciding to fall in love. Love just happens.
You can succeed in exams either by rot learning or studying hard. You can even cheat to succeed. BUT you can never succeed in love by rot learning or by dating hard. You can also never cheat to suceed in love.
You can get a good job by showing your degrees and certificates. BUT you can never get a good girl by showing your degrees and certificates. You need to prove your calibre to her.
When you die you leave every book behind. BUT you take your love with you, because love never dies.
