Life is unpredictable because anything can happen to you when you didn't expect it at all, either good or bad times always appreciate God for everything because he say there is time for everything and also we must be ready to face anything challenges we find ourselves because you didn't know when the challenges will come.
Always leave at peace with everyone even with those you know and those you didn't know because you didn't know who will help you in future.
Be of good examples to your children because they copy from your character and they try to practice what they have seen from their parents.
