And yet. I'm disciplined with money. I'm not impulsive or indulgent. I can build a mean spreadsheet. Put all this together and still the uncertainty and variability is stressful. Running down a savings account without knowing when it will be refilled is something that's always in the back of your mind, eating away at you. You build your life to fit an average yearly income - children, vehicles, rent, gym memberships, etc. When that average yearly income is NEVER guaranteed, you always suspect that this time you won't pull through, and your life will start falling apart, piece by little piece.
I can only imagine how brutal it must be for those whose skills are not as in demand or as remunerative as ours.
