Someone who I always found to be a great motivational speaker and life coach is Tony Robbins. Some people might find Tony Robbins slightly obnoxious, but I find that if you really listen to what he has to say, it can go a long way in improving your life.

Tony Robbins puts a strong emphasis on setting clear goals and maintaining a positive outlook on life.

Tony Robbins is also an advocate of continuous action. In other words, he believes that massive action is needed to achieve the desired results you're looking for. Through various methods like time management, visualization, and gratitude, you can start living a much better life.

I really find that the way that Tony Robbins emphasizes the importance of contributing to other people and giving back to the community is quite inspiring. It's not just about personal growth, but helping others grow too.
