1. Give yourself breaks when you need them. Get up and stretch. Take a brief walk. Drink plenty of water, so that you do not dehydrate.
2. Determine what you need to learn about what you sell. Determine what sales skills you are lacking. Then, take steps to learn what you need to know. Ask questions, attend seminars, read books, talk to colleagues… Do everything that you can think of to get the information you need to be effective.
3. Eliminate ‘negative noise’ in your head. When you find yourself thinking negatively–stop. Replace those thoughts with positive ones.
4. Determine the benefits of what you are selling. That is the ‘what’s in it for me’ from your prospects’ point of view. ‘People want quarter-inch holes, not quarter-inch drills.’ Focus on the benefits, and talk about the benefits.
