1. Don't be on your own in front of the TV. You know what it's like -- you're flicking channels late at night and on Discovery is some documentary or other. You justify it to yourself, saying you're just naturally curious, but pretty soon you are having rational thoughts from which you just can't get away.
2. Try to avoid walking through parts of town where you might have to pass bookstores or libraries. I remember as a teenager the lure of commentaries and concordances. Walking home from work or school, try a route that takes you past a fundamentalist church instead, even if it takes five minutes longer. It's worth it!
3. Have a block on all junk mail in your email account. I have lost track of the number of young men I have counselled who were first drawn into these practices by an innocent-looking e-mail inviting them to subscribe to a theology forum or visit a website containing "reviews" and "articles" by "scholars".
4. Be accountable. If you are feeling a strong desire to think through a given topic (e.g. a doctrine) sensibly and rationally (first thing in the morning and last thing at night are the most common times), talk to someone. Have them recite prooftexts to you. 1 Corinthians 2 is the most helpful.
5. Don't let yourself be exposed to material of a scholarly nature. Don't fool yourself into thinking that just one quick look at a intellectual commentary won't hurt, or that a peek at a book by a liberal will be harmless. Often it just becomes a stepping stone onto other, far worse material that may draw on tradition, philosophy and, at times, common sense.
6. Don't collect degrees If not required, or don't add any value, it is useless to gain degrees. People read many things which are hardly used later.It become a wasteless storage in your mind. And, you may just use it n showing other your intellectual strength.
7. Don't collect information on politics,news,movies, or games Is it adding value in you? Ask while spending time on these subjects. These areas are major time consumers of the world and it does not add any value in you. If you have career related to that area, then its fine.
8. Know your spiritual needs Are you looking for God and self realization? Then its fine to know more about spirituality. In case, your aim is help others and live more balance life then it is better to engage less in these areas.
