Thanks a lot for your useful answer!!
Now, can you help me with the usage of tenses in this sentence?
"I never thought I interested in the courses here at the festival and now I have decided I want to work in a film".
I would rather say:
"I have never thought I would have been interested in the courses here at the festival and now I have decided I want to work in a film"
Is it correct to consider "never" as a habit in the past, and for this reason use the simple past? And, why not present perfect? In cases like this, what do I have to take into account to choose one of these tenses?
Again, thanks a lot for your response.
I would say 'I never thought I would be...'. The present perfect doesn't work for me because 'have decided' tells us that the thinking is over, so it belongs in the past.
