Present continuous in English

The present continuous is a way to use verbs declaring a current action. 

For example if you do something right now, you will say: "I am doing". 

Instead of this, if you do things usually you will use the present as " I do". 

Example: 

• Something now: "I'm taking the bus to go to the office" 
• Something usual: "I take the bus to go to the office everyday in the morning"
