First of all – 20 notes is amazing! That’s 20 individual people who liked your work. When I first started writing I used to get 10 or so notes on my pieces. I’m still shocked whenever I get more than 20 or 30 to be honest. Of course it’s a nice feeling but I write for me and for anyone who wants to read my work, not for the numbers. I rarely ever check the notes on my fics. Sometimes I’ll reblog a fic of mine out of the blue because someone writes something on it and I want to save the comment or reply to them, but that’s usually it.
But that’s just me – and everyone is different.
The sooner you forget about those numbers the sooner you’ll be happier. They’re like a little added bonus, that’s all. Of course it’s really nice to see people enjoying your work. Have you tried putting your work in the appropriate tags? If you write a nalu drabble, for instance, you can tag it with nalu. Shippers are always happy to find new fics to read. :D
As for the reblog thing, I assume you mean, like, when someone reblogs their own work??? You have to remember that people usually do that because of different timezones. If I post a new chapter for an on-going fic I usually reblog it six or seven hours after posting for the people who are just waking up and might miss it otherwise. People are usually grateful for that. Of course, I never want to overface my followers, either, so I leave a nice gap between reblogs.
If people want to gain attention on their fics that’s okay too. Some people really like to get their work out there, which is really cool and takes a lot of courage, you know? It doesn’t mean they’re not humble.
But don’t compare yourself to other people, anyway. That’s not how this works. You’re an individual with your own style and that’s amazing, okay? Keep trying, anon. It took me two years to get where I am now and I still have so much to learn.
I hope you feel a little better!
