Will is used to communicate a future event. The probability of the event happening is usually high. Let’s look at some examples:

  • Tomorrow, I’ll wake up very early to get to the airport on time.
  • You will find happiness from doing what you really want to do with your life.

It can also be used to share an intention. 

  • She’ll wash the dishes in ten minutes!
  • Mr. Matthew will help you with your math homework tomorrow.
