I made a WordPress theme for Themeforest as a side project and I've failed

Hi, I'm more a reader here and love hearing about your experiences when you're talking about side project. And I thought that I could share mine this time even if I'm not that good of a writer in english

I'm a WordPress developer, living in Barcelona and working in freelance since 6 years. Ive made some WordPress theme for sell on themeforest long time ago, and one of them sold pretty good. But the interest in themeforest went away with the tons of support I needed to give people

A year ago I've started to hack together a template for my own need, and features after features I thought that I could make it better and push it to themeforest to try it again (Maybe that was my mistake, not thinking about a niche, or at least study what kind of theme people want. No, I was just making something I wanted for me). The theme got approved on 30th March and made 4 sales since

It was different with my most successful theme back then, I made over 40 sales the first day, and sold 300 sales during the first month. I'm trying to promote the item everywhere so I'm in wait and see mode but I've already calling it failure in my head. I remember a different feeling when an item hit the frontpage on themeforest, so maybe my theme is not that good after all. I'll think twice if I'll be making another one. For now even if I'm saying my self that I don't care if it fails or not, after 12 month of work it makes me feel sad. But I know I've learnt a lot doing this.

While the theme was in review at themeforest, I've started to learnt swift. I wanted to take some fresh air doing something fun, so I'm trying to make a game. And this time my fiancée is involved, she loved the idea of making a game and she helping me with the design

Thanks for reading! if you're curious I'm "kimonothemes" on themeforest
