So, imagine you're feeling a bit down or you have a big goal you want to achieve (like learning how to ride a bike). Well, a motivational speaker is like someone who comes to talk to you and gives you a big pep talk that makes you feel really excited and ready to take on that goal.
They might tell you stories about other people who have achieved amazing things or give you tips on how to stay focused and motivated. They might even do fun activities with you to help you see how strong and capable you really are.
Basically, a motivational speaker is like your own personal cheerleader who helps you feel confident and excited about whatever you want to achieve, whether it's learning how to ride a bike or something even bigger!
