1. attempt to read it the normal way, get overwhelmed
2. copy & paste the text into spreeder.com ((take the time to figure out what your ideal reading speed is and customize how the text looks in the window))
3. paste it again into ttsreader.com ((again, take the time to make sure the voice is one you actually like and the reading speed is appropriate))
3.5 if you can, try to read along with the voice as it's reading the text aloud for optimal comprehension
last tip: if it's really REALLY long, break it into smaller pieces & take breaks regularly
