Success in business is not so much about having the most brilliant answer. It is more about having a workable solution. And this requires developing an understanding of the unwritten rules of the Organization.
To become more persuasive and effective, figure out WHO and WHAT really matters. Ask successful people at your company what approaches and relationship helped them most.Be curious about the ways people get things done. And observe the inner working of the projects and initiatives you are not part of by building relationships with right and influential people.
Trust me, all of the information you gather can contribute to your own future success!!
