Required workaround when I discovered that web solutions for mobile apps (phonegap) were not that great.
This year I have started working as freelance in my spare time. I've found that this is a completely new way of working, very different to what I'm used to.
I quit my previous job because I needed some time to discover new technologies and try to develop some ideas. I saved money so I could be a few months only working on these projects. None of them was a big success though, but I learnt a lot in the process. I was so focused that I used to work for around 12 hours a day, 6-7 days a week (I was often top 5 in WakaTime). After all, I was working for myself, and a third party... and I was young, I guess.
