They say that, "Patience is bitter, but its fruits are sweet!"  And that is so true!  Learning can be difficult. But the by-product, that which comes from learning whatever it is we have learned, seems to come bursting fourth and flourishing, making all of our efforts and struggle worthwhile!  Eat of the bitterness of learning and having to change. Be patient in with the process, for things don't always happen overnight!  But know that if you labor diligently and patiently, the end results will assure you that you have not labored in vain!
