One ambition I haven't achieved yet is becoming a published author of a fiction novel. Ever since I was a teenager, I’ve dreamed of seeing my name on the cover of a book in a bookstore, with readers enjoying the story I created.
I haven’t achieved it mainly because of time constraints and self-doubt. Life gets busy with studies, work, and other responsibilities, and sometimes I find it hard to stay motivated or believe my writing is good enough for publication.
Lately, I’ve started taking small but consistent steps. I’ve joined a local writing group and enrolled in an online creative writing course. I also try to write at least 500 words a day, even if it’s just a rough draft or character sketch.
I feel a mix of emotions. On one hand, I’m a bit disappointed that I haven’t reached this goal yet. But on the other hand, I feel hopeful and excited because I’m actively working towards it now. I believe that with persistence, it will happen eventually.
