Pick something in your daily life that you want to make more convenient. Start searching for tutorials, necessary hardware, and related coding.
Even something simple like, "I wish I didn't have to turn on my fan because it's in the corner." Boom: look into building a motion sensor that runs a fan, and maybe it connects via a USB port for power.
Convince yourself it doesn't need to perfect. It just needs to create a convenience that happens to teach you something.
