I completely understand that forward thinking thing - I do it all the time! I found my first IVF so overwhelming and one of the main things I learned was that the best way to get through it was to break it down into steps and only think about the step you were on, not the next one or two or ten! The further ahead you think, the bigger, scarier and more overwhelming it is. Until I learned that I was just about ready to explode with pent up tension and worrying!

Also, when it comes to the question "how many cycles will I be willing to do", my experience is that the answer changes depending on where you are in a cycle and what happened with the last one and just simply whether or not you're having a bad day. I started out thinking we'd keep doing as many as we could until we got a BFP or as long as the money and eggs lasted. But after #3 was a BFN again I decided I needed a break to recover physically and emotionally I also wasn't ready to try for #4 at that time. Now, after a 5 month break I'm keen to get started with #4 and will be counting down to the end of November!
