Well these aren't really tips on challenging your thoughts as much as tips related to challenging your thoughts lol.
1- I often carry a thought challenging form in my purse. It's folded and all crumpled but that way if I get into a rut I can just have quick access to something that will help me challenge my thought.
2-I also use all ten questions above, I kind of know them by heart at this point. That helps me when I can't challenge thoughts by writing, at least I can do it in my head now.
3- I still find doing the written challenging to be more effective in my case hence why I carry a thought challenging form with me.
4- Also, I often have a diary with me small enough to fit my purse. If I don't have time to challenge my thoughts I at least jot them down. I find that challenging them later in the day is still helpful.
5- Finally, I find repetition helps with the really stubborn recurring anxious thoughts I have some thoughts that I have challenged more times that I would care to admit but every single time they pop up I challenge them and I find they are slowly loosing their grip on me, so if at first you don't succeed try and try again (Anyway, thats what helps me lol!)
Anyway, that is the extent of my very small wisdom on this. I would love to get tips from all of you :)
