Life is just like a dance!

"Life's a dance, you learn as you go. Sometimes you lead, sometimes you follow."

This quote means, Life is just like a dance, 

Sometimes you lead: in dance you teach or lead the people following you to the right steps & in life you also lead people, like your sister you teach her the right things to do, you help/lead her with her assignments, your classmates or your group mates, you also lead them the right thing to do so that your output/result would never be a fail. 

Sometimes you follow: in dance it's not like you are always the lead, other people would also teach you right? where did you get your steps? of course it's from other people, so it means you still followed the steps, In life you still follow and obey your parents because they know what's best for you. Your teacher also leads you and you follow right? you follow what they say because you know that all that they've taught you is not just non-sense, you can use all those things that they teach you in your daily life and maybe that will lead you to a bright and better future.
