“Above all, it is necessary for a person to have a true self-estimate, for we commonly think we can do more than we really can.”
-Seneca, On Tranquility Of Mind, 5.2
Confidence in whatever you are doing is important. But if you have large goals and ideas that you want to pursue, really evaluate what it will take to achieve those goals and execute on your ideas. Then become self-aware of your reach and your capabilities and start to fill in the missing pieces.
If you’re thinking big, chances are you most certainly cannot handle it on your own. Teams are the only way to effectively tackle execution of a big idea. Teams can make or break a project. Even if you’re someone who likes to micromanage and take control of every detail, recognize you cannot do it all on your own. Just because you’re used to doing something your way that methodology may not be applicable to a large project and can hurt a team if that’s how you’re leading it. You have to inspire, have a clear end goal(which may change) and clear smaller goals, then be a practitioner of the culture that you most want to set. Provide team members with the chance to show what they can accomplish when they are given some freedom and something important to do. You always hear CEOs say they succeeded because they had no idea what they were doing and wound up rewriting the play book. Don’t limit team members on the assumption of what they can do, let them show you what they can do. That way you get a true sense of the value that team member can provide and more often than not when they are giving freedom they will thrive.
Don’t hold yourself back because you have been a lone wolf thus far. Teams provide a ton of leverage you simply cannot get when acting on your own. You cannot do it all on your own, don’t fool yourself.
