Skipping Meditation After Great Exertion Yongey Mingyur Rinpoche, in a video, describes how some beginners exert themselves too much at once and then skip sessions. That is precisely my situation. Upon meditating for much longer than usual in one sitting, I skip subsequent days.  

Yet, recently I found myself wishing to meditate more, but not doing so because I feared that phenomenon would happen again.

How can this limitation (exertion then skipping) be overcome?

Would for example taking longer breaks between short sessions (15 min of meditation) inhibit overexertion? What would be the ideal length of such a break?
Meditation shouldn't be viewed as a need. You should neither regret that you skipped nor  wish that you do it.You are getting attached to the joy of meditation and this in itself is counterproductive to the practice.

Do it simply willingly any time you feel like it.Naturally then a rhythm will form that suites your lifestyle.

And remember that the practice should be applied in the real world.
