Do you have to attend sales courses to make a good salesman or is it related more to experience?

Thanks for invite Mrs.Tamara -

Agree with all answers sent - Especially with Mr. sameh [Smart answer]   !!!

i will give percentage 

30 % for courses &70 % Experience and attitude  

Experience is always an addition to your abilities and sales courses do help in enhancing the skills or introducing new tactics but however a good sales person is the one who is confident and innovative. Somebody with extraordinary convincing skills, listening skills, enthusiasm, and most of all persuasive. And that is something natural. It can be polished with both experience and courses.

So the answer is that both mediums are good to polish a sales person's skills.

Eexperinace it make you a salesman, but to be a good salesman you need course, training, it will help you to focus and guide you to be the best

sales courses can be a help however, actual experience and perseverance of an individual are the paramount important

Sales is a talent, but courses will help a better focus and a clearer vision. 

What would help is a presentation course since it helps how to control voice tone, eye contact and body language; this way the salesman optimizes at what he is selling

Thanks for invitation,

I do believe that to be a good salesman you have to be talented, in addition to improve this talent by training courses in order to build a very good experience in your career,  i.e you need all of (Talent + training +Exprtience)

Updating yourself with new techniques and trends is important too. Experience with updated knowledge makes you perfect.
