Even Pema Chödrön recommends we do this in her book, How to Meditate, A Practical Guide to Making Friends With Your Mind.
“Decide when you are going to get into a regular habit of meditation —and commit” (page 18).
Doing this is so much easier than our normal hemming & hawing, vacillating and perseverating.
Just decide. What do you WANT to do?
And then commit to making it work.
