I also want to be a writer. Of course writing is not easy. I have to look for references first as well as a quiet enough time to write. Writing and reading are my hobbies. So I write because I like it, but sometimes I also want my book published, and I become a writer.
I always look for the right time to write, if my mood is peaceful and serene, I always write. But, if my mood is not good, I won't write, because it makes my writing a bit bad and I can't concentrate.
I don't think you should put yourself under too much pressure. You should continue to see writing as a hobby. At some point you reach a point where you can try it with a publication. You can't force it.
I've often heard it the other way around, where writing is used to get back into the right mood and wipe away all the worries of everyday life.
You are right, but everyone is different. if I'm complaining, I always write it in a diary. after I poured out everything that was on my mind through writing, it made me relieved. sometimes part of the novel stories that I write, are lifted from the habit of my true story.
but still sometimes I feel bored. so sometimes I switch from writing to reading.
