What is your formula for success?

I drove down to New York from Boston this weekend with a couple of friends.

Driving and talking usually leads to the revelation of theories and philosophies, and I came up with the concept of success and it not being an accident, i.e. that continual success is usually the result of some unconscious or conscious formula repeated over and over. I also the you are more likely to know what your success formula consciously the more successful you are.

What is your formula?

Here's mine:

1) Belief in yourself to the point that you could reach any goal you create for yourself;
2) Momentum behind you;
3) A decision to take action;
3) A understanding of the resources you need to get there(money, time, outside help, etc);
4) A step by step guideline on how to get there with milestones(measurement);
5) A willingness to change course or tinker with the path, or add resources, etc.;
6) A healthy dose of persistence, sometimes when no-one else will support or help you and in the possible face of derision;
7) Figuring a way to enjoy the process;
8) Assuming you hit the goal, figuring a way to make the success 'portable' so you can replicate it on other projects.

Am I missing anything?
