Are two MLM's better than One?

I've tried 2 MLM's at the same time and here are a few problems I had:

1. keeping track of which person I was sending where.
2. It is a pain to have to login into multiple back offices. So just double the work load for every task, join 3 MLM's to triple it!
3. Under estimating how many people you have to talk to build 1 MLM and again just double that!
4. I love learning and training, but again there is enough to worry about 1 company and it's events.

Now, the idea of building 2 companies or even 3 is attractive to me, however I'm not the dude that can do that right now. I have heard of people maxing out there comp plan then starting with a new company while the original runs on auto pilot. And I did speak with the guy I'm referring to about building 2 companies and he told me that he would never build 2 at the same time because it is too much to take on. His advice to me was build one and max it out, then start another one after that like he did.
