Very interesting thread.

Meal prepping / cooking food in bulk saves a HUGE amount of money. Our family of 4 eats this way for an entire week for about the same cost as eating out at a decent restaurant just once.

Sell unused/unneeded items. Most people don't need what they want... and many don't want what they truly need.

Unused vehicles are a HUGE money pit.

Somebody posted a while back about simple living in a tiny house - A friend of mine went the tiny house route and it was surprisingly expensive... Some tiny homes are $50k+. Finding a place to park it with utilities can be expensive too if you don't own the land. Also worth noting that the tiny house thing does NOT work well with kids. They were really happy for about a month... and then they realized how silly it was for 2 adults and 2 kids to live in 200sqft.
