What is the most important piece of advice you would give to a fresh sales executive?

Prepare well before you go to your customer:

- Know your product

- Know your customer

- Know your self

The first impression is important to attract the customer....... positive attitude, know your product and be patient

1. Immerse yourself in whatever you are selling; become an expert at it with an answer to every possible question. That's your first lead to confidence.
2. Prepare well before every sales-engagement; do proper pre-sale research on prospect.
3. Practise your sales pitch, sales conversation skills in real life. 
4. Don't shy away from asking questions from seniors.

The best thing to remember is that you're going to hear no's way more than a yes. Dont worry about the negatives and believe in the product your selling.

be an agressive sales person and love ur products before selling them  .

learn your product

educate your client

Result: sales success

As compared to above people, i am just a novice but here are my takes on the topic:

Dont enforce your product on the customers. Look from their perspective, give them a way out and persuade them.

Everyone above is right about knowing your own product but i would suggest creating a story behind it. Products with a story go far ahead with customers.

Practice story telling not the usual sales pitch and most importantly tell your customers the benefits of your product along with the shortcomings. This makes you look natural and honest.

Provide them with reviews and ratings from authentic influencers or people they know. Both milennials and baby boomers love it.

Oh and dont forget to use graphics for your pitching. People love pictures and videos. 

To be Honest and punctual to your job

From my point of veiw (( Must Know What you Need )) to work on it to achive your goals , meaning you MUST know what you want to be in order to plan you life time to reach that not only in work but in all your life time.

From the first day, you will know if you`re cut out for it or not, and if you are, Don`t give up.
