What advice do you have for your grandchildren? Advice for your grandparents?

I am copying these questions directly from the cards.  I say this because the second question is silly.  All of my grandparents are dead.  All the good and bad they can do has been done and their children and grandchildren are the indirect products of their actions.  That is humbling to think of that we as parents can have an influence on future generations by our action or inaction.  Something that we say in anger can taint our children and be passed on to our grandchildren.  Innocent words can be misinterpreted to leave permanent impressions.  Failure to act can leave scars.  None of us are perfect and we will make mistakes and must learn to forgive ourselves and make a mental note not to repeat our errors.
Advice I would give to grandchildren.  That is a very serious question that will take a lot of thought.  First, life is not easy.  The easy way will yield bitter fruit.  Nothing worth having comes easily.  Work is not a four letter word.  The joke about "How do you get to Carnegie Hall?"  "Practice, practice, practice." is more true than funny.  That is how we get to our goals.  For some of us, we won't have to work as hard at first but don't use that as an excuse to be lazy because there will come a time when it won't be easy and if you haven't prepared yourself to work, you will fail.  Resting on you laurels can become an uncomfortable bed.
Second, respect your body and mind.  These are the only things you will have your entire life and the only things you can rely on during your lifetime.  How do you respect your body and mind?  Provide it with proper nutrition and exercise.  Do not abuse it by using substances proven to be detrimental to continued good health.  Keep your weight under control.  It is rough carrying around extra pounds when you are old.  Keep yourself clean in body and mind using soap on the body and self control for the mind.  Is it easy? Of course not.  That is from the first point--Life is not easy.  Is it the trendy choice? Of course not.  Is it the best choice?  Yes.  It is the one that will lead to a long and healthy life.
Third,  Find a direction and something to believe in.  Without direction, we wander and without something to believe in, we flounder.  We all need an inner compass to keep us going on the right path and a strong belief to make the trip worthwhile.  My belief of choice is God and my compass is found in His Word.  Yours may come from something or someone else and that is your choice just be sure it is a true direction and belief and not a false one that will lead you to destruction.  We have been given free will so that we have the right to choose our own way.  Use that gift well so you will have a good and useful life and be a credit to yourself, your family and your country.
