Reddit mentions of The Llewellyn Practical Guide To Psychic Self-Defense & Well Being (Llewelyn Practical Guides)

I had great success with the Tower Of Light ritual, which is described in detail in Denning & Phillips's excellent Practical Guide To Spiritual Self-Defense. They prescribe daily use of the exercise for sensitives souls like you. :)

As a practicing magician, I rely on daily use of the Ritual of the Pentagram, adopted for my identification as a Thelemite. A Lesser Banishing Ritual in the morning and a Lesser Invoking Ritual in the evening have worked wonders over time. The ritual is described in clear detail in the article "It's In The Basics: The Pentagram Ritual", from The Black Pearl, vol.1, no.3, on page 14., available for free online from Temple Of Thelema.

Work smarter, not harder.

Will is a resource that needs to be conserved and used wisely. If you want to quit smoking, but surround yourself with smokers, you're going to waste a lot of willpower.

These are two classics that I like. I think they're a good buy and helpful and they basically describe what I do. Some of what I do is personal, related to religious training. I don't want to get into that. These offer a decent foundation. Both of them are pretty old but good to start with I think.
