This might sound harsh but, who cares about motivation. I'm not motivated everyday. But what makes you stronger is doing things when you aren't motivated. But I also believe in what marcusverus mentioned. Also, you do not have to spend hours on a task. Try to do one small thing a day or every other day. Could be 5 mins of learning, coding, or reading. The other day, I was not motivated to work on my side project. But I needed to know how some small part of an external API worked. I dedicated 5 minutes to reading the docs. That 5 minutes turned into me implementing the whole thing. You never know where a small bit of work that you do not want to do will take you. Just my two cents.
