Planthead,

I consider my job the most important asset I have (whether I like it or not is a different discussion....).

The main component of my ticket to an early retirement (or at least I am hoping so!) is the interest compound on my earnings (i.e. savings from my job).

Let's say you are 27 years now and you save 15% of your salary -assuming a decent salary which also increases on real terms every year, this is the key part...-, with an average return on your investments before retirement of 6%, you have a pretty good chance to have a decent amount to retire when you hit your mid 50s (obviously if you want to retire when you are in your forties, then follow the others' advice and set up your own business).

Please note that this will combine with other assets you build during these years, such as the house you might buy, a few extra savings in pension, the occasional bonus, etc.

No magic in there, just pure patience and discipline.
