Doe’s life is unpredictable?

It's my experience that there are several factors that can be stable or unstable, yet not all at once:
Personal life
Work life
Family life
There is a relationship between the three and an interaction.
Often when one of the components is unstable (by choice or circumstances) the effect will drag into the other components. What you want to avoid is that all three aspects are affected at once.
When you are single, you have only personal life and work life. If that's the case, nothing holds you back to lead an adventurous life. There is no real insecurity in this when you have the right type of character. In the past I easily quit jobs even when I had no direct sight on a new job. I'm confident that I find a new job.
When others get involved, wife and kids, things change. When I quit my job
Take a different approach. Nothing in life is straightforward.
So if you think that by bluntly poking around you will find your answer or solution you are wrong.
Always try different methods or at least experiment with different methods or solutions until you get the right results.
