This is so true. One's expenses always grow in accordance with one's income.
It is a pity that wisdom comes with age. By starting young: putting away regular savings and learning good financial discipline, you could set yourself up so much better for the future.
I took my first house loan out when I was in my early 20s. Before that, I didn't care at all about expenses, I was wild and reckless with my money. That taught me a lot about financial planning in a very short space of time, but it would have been great to know it sooner.
What really taught me how to deal with money was when my relationship ended and I lost half my stuff! Then you learn how to save and plan at a whole new level! 😂
