With business getting busier and faster than ever, it's all too easy to lose motivation when doing our day-to-day activities. Regardless of just how motivated each of us may be, it can be easier to give in to procrastination and laziness. Read on for some great, inspirational TED talks to get your blood moving and keep your motivation strong.

1. Dan Pink: The Puzzle of Motivation

Career analyst Dan Pink delves into the traditional reward system, especially when put into play at a professional workspace, and why it often fails us. In his talk, Pink presents a number of scientific studies in order to affirm what we already know: We need to do things that matter to us. When we're performing actions we don't care about, or toward which we have no emotional attachment, it's incredibly difficult to stay motivated.

Traditional schemes, like if-then fallacies and narrow reward strategies, can occasionally work. But in return, they stanch creativity and cause us to miss innovative solutions. Thus, we must motivate ourselves by finding passion in the things we do. It's the answer our hearts knew all along.

2. Tony Robbins: Why We Do What We Do

Life coach and business leader Tony Robbins demystifies the "invisible forces" that cause us to do the things we do -- from impactful life-changing decisions to the many small, mundane habits we do every day. Robbins touches on how our models of the world and our basic human needs shape the decisions we make.

In his interactive discussion, Robbins gently prods the audience to realize how much they value six basic human needs: certainty, variety, significance, connection and love, growth, and giving back. Despite where each of us may stand in relation to each of these values, it is clear that exploring our own basic emotional needs is crucial to understanding the reasons behind our actions -- as well as the actions of others.

3. Scott Geller: The Psychology of Self-Motivation

Virginia Tech professor of psychology Scott Geller discusses the logic behind boundaries -- and how to break them -- in his informative talk. By breaking down the reasons and thought processes behind our ability to self-motivate, Geller allows us to figure out what works and what doesn't.

He implores the audience to keep in mind aspects of choice, consequences, and community when making decisions. Knowing that we're all in this together is sometimes enough to get us going, and Geller, through his comprehensive talk, reassures us of that fact.
