I am learning English. I found this sentence in a book.
At the time, I was struggling to establish myself as a writer and to follow my path…
Is it grammatically correct to use the to-infinitive and.
That’s a correct usage.
What you’re doing is omitting the part [I was struggling] from the sentence:
At the time, I was struggling to establish myself as a writer and
[I was struggling] to follow my path….
Since repetition would be redundant there, it’s supposed to be omitted.
