Forever Skill No 4: Laugh at yourself
The journey from confidence to over confidence to arrogance to downfall is like a chemical equation. it may take time but it will happen. Best skill to safeguard against arrogance is a sense of humour not at the expense of others but at ourselves. if you are struggling for material ask your spouse, kids, parents, peers, teammates, pets for fodder. Be prepared to be amazed. if you want to be taken seriously, don't take yourself too seriously.
