Be absolutely faithful to your daily commitment to read Braille. When you feel comfortable reading this new amount, increase it again and make that your new goal. Be sure to read every single day. Remember, it does not hurt to read more than the minimum you have set. If one day you don't meet your commitment to yourself, don't worry about it.
Stress causes burn-out.
Just begin where you left off and continue achieving the same goal each day. Begin with very short passages. It does not take long to be able to read a selection of three or four pages in one sitting. It feels wonderful when you can say that you have read a whole story. Such success encourages other attempts.
