When in doubt ask good questions and leverage the knowledge and experience of other people. There are few things less attractive about a leader than someone who acts like they know the answer when they don’t. Confidence can be a good attribute but hubris is not. People ultimately see through your words and pick up pretty quickly if you simply make it up as you go along. More importantly, those around you who do have the answers lose respect for you and begin to question everything you say.
No one is ever successful alone. Whether it is at home or at work you need other people to buy into and ultimately support your success. You need to think of the people close to you as part of a winning team that is committed to a common goal, which is each others success and happiness.
