If else not running on Boolean value

Tried the below code. All I can ever get is "not working".

bp_is_my_profile();        //this is a Boolean.
echo bp_is_my_profile();      // this echo's out either one or nothing depending on true or false.

if ($bp_is_my_profile === "true") {      // I've tried putting in numbers one and zero.
  echo "Have a good morning!";
} elseif ($bp_is_my_profile === "false") {  // I've tried without quotes.
  echo "Have a good day!";
} else {
  echo "Not working";      //whatever the Boolean is, each's it prints this line of code.
}
