NOTE THE DIFFERENCE
PRESENT SIMPLE with always / constantly / continually means repetitive actions, e.g.
I always have meetings with clients on Mondays. (fact)
PRESENT CONTINUOUS with always / constantly / continually shows annoyance or criticism, e.g.
I am always having meetings with clients on Mondays. (I hate it)
Now it's time to practice using these tenses correctly.
PRESENT SIMPLE and PRESENT CONTINUOUS for THE PRESENT
Use present simple for permanent or repetitive actions, e.g.
Tomas always delays paying his bills until the very last minute.
Use present continuous for temporary actions (not necessarily happening at the moment of speaking), e.g.
Tomas is working on his project this week... or at least staring at it.
PRESENT SIMPLE and PRESENT CONTINUOUS for THE FUTURE
Use present simple for future timetables, e.g.
The meeting starts at 9.00, but Tomas is always late for it..
Use present continuous for future arrangements, e.g.
Tomas is meeting his boss tomorrow, but he still hasn't opened the report.
