What I've learnt from this challenge is that it isn't really about making huge cuts to the things that you love to do or buy. The most money I saved was simply from thinking about what we NEED and planning/researching before I bought anything/went anywhere. The thrill of "making do" or finding the cheap/free option over spending money was addictive.
I sold a few things on Gumtree and made a few hundred dollars. I did a lot more DIY (like cooking, gifts, my own conveyancing (property transfers)) and saved thousands in the process (the conveyancing saved me $1100 in professional fees alone). So for a little hard work, I was able to achieve more than just savings on my hip pocket, I also learnt a few new skills (thanks to the internet! You can find out how to do just about anything online.)
I feel like I've reset my financial frivolity and ongoing I'll be a lot better about sticking to my budget and not making unnecessary purchases. That said, I'm looking forward to being a little more flexible and allowing myself to do the odd discretionary purchase again!
So going forward, I don't plan on being this "tight" with money every month however I do plan on doing it every few months because it was a great exercise for getting ahead a bit. Now I feel like I can face the silly season. Bring it on I say!
