If you know how to use the PhotoReading system you'll be applying the 5 day test approach to your books, textbooks and reading material anyway. If you're spending 30 minutes a day on activation you're well on your way to activating a book per week.
If you're already activating your study material what are you worried about activating for? You're already doing it.

If you are using the system well and making advances in your studies, is more really necessary right now? Can the ego not wait for spontaneous activation? It happens in it's own time and for people who are more consistently using PhotoReading than those you only do it occasionaly. You can always do the push when you have more time. But right now you need to consider your priorities.
Once you've applied the 5 day test/experiement to 3 to 5 books not related to your studies. You know how the system works and can confidently apply it to your studies.
