As an employee it's easy and even expected for your supervisor, team lead, manager, whatever they are called in your organization, to direct you and tell you what tasks to accomplish. Please understand that the work doesn't always have to come from their direction, take INITIATIVE! That simply means to seize the opportunity to act before others do...so before anyone has to tell you to do it, just do it because you can see that it needs to be done.
Being an entrepreneur is the ultimate act of initiative. Whether you started a non-profit, e-commerce business, or a small start up, you saw a need and you set out to meet that need. So no matter if you are the boss or the employee there is nothing stopping you from taking initiative because in most circumstances it will be appreciated and met with smiles.
