Can a author write other series?

Hello! I want to be an author someday and I have some ideas for 2 series which are coming of age novels. Since you’re a real author, I thought I should ask you, Can an author write more than one book series in their career? Can both series be coming of age series? thank you for reading my letter, have a very lovely day!

Authors can write whatever they want, and publishers publish what they want.  You can certainly write more than one series.. I’ve written a half dozen or so, but they are all different from each other.  My advice is to work on one at a time and don’t worry about the other one.  You may find you’ve used up your best ideas in series #1.  If you write one series and it’s published, then another series that deals with the same topic–and they are too much alike–your second series would be competition for your first.  In my opinion, it is so much better to concentrate wholly on one book or series at a time.  Writing two books at a time is akin to delivering two babies at once.  Neither gets the full attention it deserves.
