Sometimes we fear losing things or we fear losing a job when we take a particular risk. Tell yourself, what is the worst that could happen to you? What would happen if you lost everything? Will you still be able to live or survive? Will you still be able to find some sort of income somewhere and all you had to do is to minimise spending and your lifestyle?
Most of the time, that is the case. Most of the time, we can survive. All we have to do is sacrifice a little.
I guess another part of it is to prepare for the worst. To be at your worst is to prepare yourself when it actually comes.
