What is the key to success: talent or devotion?

I would agree with many of the prior answers.  Talent and devotion both have a role to play in success as do many other factors including persistence, adaptability, team, and luck

Both talent and devotion are important for success, one complements the other.

As per my personal experience, two things are more important than that in the real world today. They are nationality and skin color.

I have been teaching Science and ESL for years, including3 years of Science teaching in United States and2 years of ESL teaching in Oman. I am an Indian and I have applied for more than a thousand vacancies,  which you can consider highly paid and respectable. In most of the cases, I get no response and in few cases, I get a polite negative answer - we employ only native speakers of English or we employ only citizens of United States, UK, Australia, New Zealand, Canada and South Africa. I have lost faith in the equality of human race.

Apartheid has virtually disappeared from the planet earth but it has taken another form - only native speakers of English.

I Believe that the key to success is Devotion.Talent, I believe is inborn.Everybody is talented in some way or the other.The key is the Ability to Learn and Adapt,The Ability to Improvise.This is only possible if you are DEVOTED to your goal and you are ready to put in all the hardwork to prove your Talent.THUS THE KEY TO SUCCESS.

there many factors of success  in addition of these tow factors like work hard learn more self confidence and help other poeple without anxiety

 The key to success is to be talented enough and devotion is one of the pillar of Talent.

It does not matter if you are devoted , loyal , adaptable trustworthy  or anything if your not the correct fit in someone's eyes who has influence on the hier people who have the final say then your history no matter how good you are ,Mike

i  think  the  key  of  succes  is tallent ,devotion  and  love  

so  when  you  have  a tallent  but you  have'nt a devotion  and you  d'ont  love  this  work  you  can't succes .

My opinion is, it is more of a talent, because no matter how much you are devoted, it won't be as benificial for the company if you lack the talent to do certain task. Subsequently, I would give more weight to the talent. For example% of talent against% for devotion.

To be more precisely answering or giving an opinion we should ask the following : if we are talent as an assumption what are the rewards of being devoted if there is no respecting to the talent from the employer ?!! If there is no respecting means devotion is just wasting of time in the company and it is better to find a place were you could apply the both. However, devotion must be in all cases because it would refine the talent in some way and without it the talent would not be used as it suppose to be. 

Talent for sure, if you have the talent it means you have the passion

Both are like two human legs. If you have talent and devotion you will be stable on ground. One complete other in road called sucsess. Thank you !
