Dear Madam,
It is on a few occasions only I like and I incline to participate or replying to some posts or discussion in the forum.
The individuals being bundle of emotional feelings -- anger, happiness and sad-- are controlled by these very emotions. No one is exception to application of these feeling one way or the other in daily lives. An excess dosage of any of these basic feelings displayed by us in any situations will empty our commonsense gradually or quickly. The excess or display of this disturbs one's normal self and it takes efforts and time to retrieve to normal mode. Similarly the arrogance is extension of our ego or our own reasoning for a cause known to the individual only. What is simple application of reasoning or logic is downright arrogance to some one. On the other side in our mind chemistry anything excess including confidence is not good for self and for society which is a group of individuals.
Confidence is the ability in applying known capabilities for positive outcome. Again this is a relative term because it is subject to situations and individuals profile or life styles. Over confidence leads so many negative effects in any walks of life. Arrogance is a reflection of our rigid stand under any situations without giving leverage to plus and minus of our analysis or judgment. Simply it boils down to adaptability to people and situations.
Successful people whether it is in personal or career life, have this adaptability to maneuver the rough situations and people. Many top leaders have failed successfully because of lack of this single most important attribute.
It applies to more youngsters because obviously they have just not seen many situations and people. Success misleads them. Success is taken for granted. It is only a milestone and in the journey of life there are many milestones, ups and downs, terrains, roadblocks, surprises. Success and failures and -- only failures-- mould us to take on life.
best wishes and have a good day.
