1. Low expense lifestyle. My family has moved and managed to reduce our expenses and rent to zero. Insurance, groceries and petrol are now our biggest expenses. Try to tackle the expenses with a once off downside in exchange for an ongoing upside. Avoid cutting expense where they require the opposite.
2. Give yourself time. I've had to spend a few hours each day working on the business in order to get to this point. This meant I had to reprioritize a few things. Easy to eliminate things like TV and sleeping in were out. Just those 2 things enabled me to gain the skills I needed to start earning a basic level of income before ever taking the risk of going out on my own.
3. Have a backup. I put in a simple backup plan in place in case everything goes horribly wrong. I plan to go back to my former employers and ask to sign onto a contract for 3-6 months. I am able to earn enough to cover my yearly expenses in that short period and then I would go back out on my own. I made sure I didn't burn any bridges and I did quality work until the very end, just to make sure I'm welcome back. The backup plan gave me the confidence to strike out on my own knowing I could always take care of my family.
So that's it. 3 things I did to move me to the point where I am completely comfortable being out on my own. They aren't difficult, but they may be emotionally hard, especially if you are attached to an area or are really addicted to TV. It's something that needs to be overcome on the path to your success, so I suggest you start working on each of them today.
