<p class="os-raise-mb-0">Proactivity is the ability to take initiative. There’s evidence that proactivity is one of the qualities that distinguished the greatest American presidents from their peers. </p>
<p>Think about your current sense of proactivity. Are the following statements are true for you?</p>
<ul>
<li>
I am always looking for better ways of doing things.
</li>
<li>
I love to challenge the status quo.
</li>
</ul>
<p>Don’t worry if none of these statements are true for you. Developing this trait takes time. Your first step starts today!</p>
