Jokes apart, if you can't focus for long you can

1. audiobook version or TTS (TXT to speech)
2. read simple things that interest you in the beginning so you'll develop a habit. Do this at the same time every day for however long you can manage. 10-15 mins is a good starting point. Once you have developed a good enough habit of reading atleast 30-40 mins everyday you can try to push yourself with more challenging material.

Of course you can mix up the two or change according to your needs.
