When you are discussing working with someone, make sure the company or the person you are planning to work with understands the value you would be bringing to the work.
Unless it is clear what value you are bringing, people would have questions and doubts prevailing. Let them clear their doubts before you move ahead. If the doubts persist, its better to drop the deal.
Always have clarity before moving ahead to prevent confusion later on.
Think Big. Be Wise.
