Today's topic is productivity.

I 'm gonna talking about productivity.
I started to work as an engineer since April, so I'm interested in productivity.
I think productivity is how you spend today.
Have you felt today was more satisfying than yesterday?
I always want to say ''yes'' about this question.

By the way, are you a very motivated person or do you wait until the last minute to do things?
As the matter of fact, I am latter. But I have become a more motivated person since I started work.

I want to know how people can improve productivity.
A tutor who taught me English said ''there are three ways to do this.
They were management, immediate superior, and dependents.''
What she said was very informative.  ("For me" is not necessary)

Wow! It is high time I went to bed. ww

Good Work :)

today's topic is productivity

I 'm gonna (going to) talking about productivity.
I started to work as an engineer from April, so I'm interested in productivity.
I think productivity is how you spend today.
Did you feel today was more satisfying than yesterday?
I always want to say ''yes'' to this question.

By the way (incidentally), are you a very motivated person or do you wait until the last minute to do things?
As the matter of fact, I am the latter. But I became* a motivated person when I started work.

I want to know how people can improve productivity.
The tutor who taught me English said ''there are three things.
They are management, immediate superior and dependents.''
What she said was very informative for me.

Wow! It is high time I went to bed.

I'm not sure what you mean?

'by the way' is fine. 'incidentally' menas the same but is more formal

* This is a completed action in the past so we use past simple. (You could say 'but I have become a motivated person since i started work.' if you want to use past perfect.)

This isn't necassery
