This is life
No one has ever fallen. Everyone has felt it. how painful he felt, made him weak.
When he gets up, his business will start from scratch again. Starting a business from scratch is not as easy as turning the palm of the hand, there will be a period where he will fall back. When falling, do not despair, keep trying, someday there will be a time you will succeed and never fall again.
See the baby who is learning how to walk. When he falls, he rises again, falls, rises, falls, rises, tries his best to walk on two legs, never to feel tired despite the pain he feels. Make the pain as a medicine in your business.
NEVER GIVE UP.
Do it.
