There are many ways to do a certain thing or job. It is good to get as many advices from different people who have the expertise on that matter. The book of Proverbs provides many advices on the need to get many good advices before doing something. Especially if you are thinking about venturing into a new business or new job or new missions.
However, there will be times when you need to act alone. If the situations warrant immediate decision you need to act fast. You have to make that decision, alone. Or you have to be the one who spearhead the project. This is the time when you have to be the "lone ranger" making sure things are done according to your plans. You can't depend on others to do the job as that would slows down the momentum. If you want to go fast, go alone.
