More truthfully, this is  “How to Take Maximum advantage of the rules in Mafia Wars”.

If you play correctly, you can get to a point where you will never run out of energy.  You can just level up over and over and over.

Today I played for just a little while and completed over 4,800 jobs:

This is what you need to do:

1. If you haven’t started yet, choose the Maniac mafia type.  This isn’t required, but just makes the game go faster.
2. Find a Mafia Wars group to find people that will join your mafia.  Send them friend requests and start to fill up your mafia with the highest level guys.  The two most important slots to fill in your Top Mafia is your Mastermind and Wheelman.  I made sure I filled them with guys that gave me an 11% reduction each:
   
   This gives me a collective 22% bonus for all my jobs – HUGE.

   For your Mastermind, you are looking for someone that has completed a lot of jobs, and for your Wheelman you are looking for a high level Fearless mafia type.

   My Mastermind has completed 27,500 jobs, and my Wheelman is Level 358.  These are high numbers, but relatively easy to find.

3. Add every skill point to your Energy as you aquire them.
4. Whenever you can, spend 14 Godfather points to receive 4 additional Skill points, and add them to your Energy.

It won’t happen right away, but eventually, you will have so many Energy points that you will never run out.  I was able to complete all of Cuba in one sitting, along with most of the Boss level.

Once you have completed all jobs, there is no end (at least so far).  You can complete the best paying job, “Settle a Beef…Permanently” forever. I levelled about 100 times today alone.
And just to show you how cool it is, I completed jobs for the same amount of time it took me to write all this up (about 10 minutes). This was where I started:

And after 10 minutes:

It would take a normal player well over a week to complete 30 levels!

Every “trick” has a down side, but in this case I don’t think it is a big deal. Because you are spending all your skill points in Energy, you will be very weak and get robbed and killed more often. But since there are no real penalties, this is a small price to pay.
