I now have 20 short stories published. Wow. I can still remember trying to get one published somewhere. I would've been happy if someone accepted it anywhere! My first accepted and paid submission was a silly sci-fi drabble (a piece of exactly 100 words). I still have that dollar sitting in a frame beside my desk.
I tried getting published in my late teens, but the first rejection destroyed me. I didn't try again for about 15 years. Maybe age toughened me up, but I kept pushing on past the rejections. I kept submitting. Now I have 20 short stories published.
I still get rejected. Some hurt more than others, but I keep pushing forward. Perseverance does pay off.
Never give up on your dreams!
