This is something I am sure we have all heard from parents, friends, bosses, from many people.
However, good things do not have to come to an end, it is a choice and it is a mindset.
It is also about not living a life where we need ‘good things’ like a holiday or something to get us through the struggle that is the rest of our lives. We can choose not to accept the struggle in return for brief periods of better times.
Life is a good thing, so yes, that will come to an end, other than that every day is a good thing if we choose to make it that way.
