One source of income is just a moment before the crisis, be it an investment or a great job. What you can do is to have multiple source of income which can be multiple jobs or one job, one part-time business, one online social media account or etc...
And people saying I am very comfortable with just one income from an average job is just a big fat lie.
They just haven’t yet faced a situation where they’ll be fired from their jobs. That’s when they’ll realize just how mistaken their view of the world and their own situation really was.
I was exactly the same naive guy who, at a young age, made plans for my life based on having a good job, but everything turned upside down in an instant when my boss asked me to write a letter of resignation. That’s when it hit me. I realized that nothing in this world is permanent, and that relying on a single source of income puts one’s very existence at risk.
You have to do everything in your power to create multiple sources of income. Yes, it won’t be easy, but it significantly reduces the risks. Will it be hard? Undoubtedly, but only at the initial stage; after that, you’ll just have to adapt to the circumstances and find compromises along the way.
