What is a one-sentence summary of the following article?
One aspect of good leadership is being quick and decisive to act to solve a problem. If you see something needs to be done and are confident that you know the best way to do it, use your initiative. A strong leader can be someone who is prepared to take the lead in situations without necessarily being asked to.  Using your initiative demonstrates a positive and “can do” attitude.  Make sure you are confident in your actions, however. Act calmly and assuredly, and don’t ty to rush to a solution when the problem requires consultation. Another aspect of good leadership is knowing when to take advice, and understanding when a problem needs a deeper understanding before it can be addressed. To set a strong example as a leader it’s essential that you take responsibility for your individual tasks and priorities as well as your team as a whole. Having clear priorities and clearly assigned roles will make it easier for people to identify and own their responsibilities.  Support your team members to complete their tasks and try to forge a cooperative rather than a competitive environment and culture.  Taking responsibility can also involve removing responsibilities from those who have demonstrated that they are unable to manage the tasks assigned. One way to demonstrate good leadership skills is to always be alert to new possibilities to learn and develop your capabilities. Showing a continuous desire to improve yourself and your work can be a motivating factor for those around you. It demonstrates your commitment to excellence and your lack of complacency.  Organise and write down a clear set of standards for yourself personally, and then try to always stick to them. Try to monitor your work, and identify the areas which you can improve on. You can use these personal standards to draw up a personal development plan. A good leader is someone who can provide a clear and compelling vision for the short term and longer term future. The ability to plan ahead, think strategically, and develop priorities are all hallmarks of strong leaders. In order to do this, you will need to develop a broader perspective so that you can see beyond the immediate deadlines.  Seeing the bigger picture can help you envisage problems before they arrive. This kind of approach can also lead to innovation and structural changes that have long term benefits.

Summary:
Use initiative. Take responsibility. Keep improving your skills. Provide a vision.
