Good ones, Teacher, way to go indeed!

   This reminds me of Marianne Williamson quote  "If you give your live a wholehearted response to love, the love will wholeheartedly respond to you".

  -----------------

    I will offer the following sentence, as a hunch of mine.   So it may be improved, altered, rephrased etc.    Up to you English speakers; tought it may have a better (or more natural)  way to express the same thing.

    Teachers, advanced or intermediate learners, the ball is in your court now, comments are appreciated.

    "Tough we never know if a relationship will be lasting, we must be whole-heartedly in it."
