Why do you have to use present tense?

Answer 1

To make your writing and your speeches more presentable

Because we use different tenses to talk about things that happen at different times.

For example we use present simple to talk about things we do again and again (habits) e.g

I get up at 7:00. I go to the bath room and then I get dressed. Then I have breakfast.

We use present continuous tense

- to talk about something that is happening now e.g

I am answering questions on wiki answers.

- to talk about something that will happen in the future e.g

I am working this afternoon. (now it is morning).

Answer 2

Using present tense when describing steps or procedures helps to provide clear and consistent instructions. It creates a sense of immediacy and helps the reader better visualize the process as if they are actually performing the steps in real-time.
