I decided that I wanted to build something of my own, but what...
Well, the email forwarding service that I used at the time was acquired by another company and got bloated with unwanted features and things. I longed for the simple service that I was used to. I toyed with the idea to just build my own service/app that will fit my needs.
This was probably my first mistake. I did not come up with a new idea, it was something that already existed, I just wanted it to be simple again.
So I spent some time thinking about how I wanted to solve this problem for myself.
