If you abandon your house for long and nobody lives in it, it will depreciate.
It goes same for your muscle, and brain power.
If you possess a good character trait like courage, and you don’t use it, you will lose it.
A driver who doesn’t drive will find, on starting again, that the skill has dwindled.

You have to keep using your talents, your skills, and your physical and intellectual attributes to keep them strong.
You will realize, if you go off blogging for a long time that you will have to put in quite some effort to regain your skills.
All this underscores the importance of permanently using the brain, the talents , the skills and qualities that God has given us or that we have acquired, otherwise, we lose them.
Knowledge is not meant to be stored away on a shelf but to be used to do things.
Use your knowledge and whatever skills and talents you have to get the results that you desire.
