I was in your situation 6 months ago. I was well experienced in HTML, CSS, JS and NodeJS but wanted to learn React too.
What really got me going was doing one project for my customer. It was a good basis to learn React in a real environment and it got me rolling.
I can only advice you to do some REAL projects, not a a tutorial to-do list application of sorts: these won't teach you around hard stuff to handle as they are very controlled.
Go out there, create a real application for a business or as an intern somewhere. :)
