it means আপনি have to make your own experiences and mistakes and have them your self, no one else can do that for you, they may tell আপনি mistakes they've made but that's not an experience for you and আপনি likely won't take it to হৃদয় unless আপনি do it yourself.
it means be yourself, do anything right through your deepest heart... no one can make আপনি the same thing অথবা feel the same thing like আপনি do... don't hang on someone all the time 'cause আপনি might be alone other time :)
