Well, the first step is realising that you need it. You realise that you've been cruising complacently through life, taking the successes and the failures as they come and hoping to be rewarded by your superiors for your hard work.

You then have an epiphany where you realise that you can be responsible for your own destiny, follow your dreams and create your own wealth, thus freeing you from the shackles of mediocrity and your "career".

After this epiphany, you start to see the world differently. It's ripe for the taking. You will begin to see opportunities where you saw nothing of consequence. You will begin to see how almost everything can be leveraged in some manner to help you pursue your current goals. Your passions will lead you to do socially ostracising things such as quitting your job to work full time on your own projects for six months before you make a single cent in profit, but you won't care. Your passions and the freedom to pursue those passions are more important than anything now.

This is how it was for me, anyways. I'm about to hit the one year anniversary of jettisoning my programming "career". :)

Well put. Hustle is not principally about hard work, rather it's about resourcefulness- encountering an obstacle or finding yourself stuck in a rut, and having the mindfulness, wit and unabashed boldness to hustle your way out of it. The "epiphany" is what it's all about, once you realize that we build artificial walls and barriers everywhere in our own lives, it is so empowering to plow right through them.

So here's the short version of how I got my hustle. My life used to suck in the sense that I wasn't living the life I wanted. I wasn't good at lying to myself, I knew something was wrong, but I couldn't figure out what it was. After months and months of soul searching, I finally figured out what was truly important to me. I realigned my life in this new direction and all that pent up energy caused things to just take off.

If you try to hustle through a wall, it feels like you're standing still, but once you try hustling around or over it, things start to move. I'd say identifying your wall is the hard part, but getting around it ain't no picnic either. That being said, nothing compares to running free on the other side.

Probably by realizing the person ultimately able to determine success is the one in the mirror.

It does sound silly ("Millionaire Fastlane" pff), but this book is actually quite amazing for realizing what it takes and how you can hustle your way to real success (not necessarily just financial success) http://www.themillionairefastlane.com/
