2) and to talk about our hobbies, timetables and things we do regularly.

Present Progressive (short-term)
1) We use the present progressive for things that are happening now.

2) and for things that are happening around now, but not perhaps at the exact moment.

3) and how life is slowly changing (+trends)

We normally use the present simple for things that are long-term and the present progressive for things that are temporary or different from our normal lives.

show us how often something happens. We often use adverbs of frequency with the present simple. "Do you always drive to work?"
We use adverbs of frequency:
* before the main verb "Penny never reads the paper on her way to work."
* after the auxiliary verbs be, have, do and modal verbs such as can, will, must, etc. "Frank is often at the gym in the afternoon." "You can always count on me."
