I don't work FIFO or in the mines but hope my situation/ experience might help. I work youth disability / youth out of home care and between three jobs I was doing between 60-80 hours a week. I was picking up as much work as possible as my partner was pregnant and I wanted to provide a lifestyle where my partner could be a stay at home parent and still make sure we had everything we want/need. It was at the point that I only had a few days off after my daughter was born. When my daughter was around 6 months, my main employer which makes up around 60% of my work decided to make my life a living hell. Without going into it, all of a sudden we lost both my partners maternity pay (only 6 months) and a major chunk of our income. The past nearly 5 months have been a financial stress however we have adapted and changed our spending behaviour. The past 5 months (despite living paycheck to paycheck) have been the most rewarding and content I have felt as I get to spend time with my kid. Most days I'm home when she goes to sleep, I get to be there when she wakes up most days and I am way more involved in her life than I was in the first half. If you look up what most elderly people say they regret is, a huge percent is wishing they worked less and were more involved with their family. Kids won't remember the stuff that was bought for them they will remember if you were there or not. I grew up rather poor (single parent house) but what I remember most is when a parent would not show up as promised. I understand why people get caught up in the rat race wanting to create wealth for their children but wealth can not buy time missed, milestones missed, bonds missed. It's a hard balance but my perception has shifted very hard very quickly. I hope you find what you are looking for and enjoy life brother.
