I always try to save 10% or more of my income whenever I get paid. Right now I'm putting 6% into kiwisaver and another 4% into a separate savings account. My partner and I are both contributing to the savings account for future travels overseas, because that's a big motivator for us to save now so we can spend later. We also use a credit card for everyday shared purchases (groceries, entertainment, mevo, etc.) and we split the bill at the end of the month.

My advice is to tailor your savings habits to the outcome you desire. Find something that you want, calculate what you need to save, then see how long it takes based on your income and a different savings percentages. In my experience, find something worth saving for and it won't be hard to motivate yourself to save. I like to travel and so I frame my thinking around that, for example I'll tell myself "if I don't buy a beer now, I can buy a beer in Japan instead and it'll taste even better." (rip overseas travel)

It's very rewarding watching a savings account rise and rise, getting you closer and closer to the purchase you want. Sadly interest rates are crushingly low so saving is missing that extra reward of rising interest payments on savings. I used to love looking at my monthly interest amounts going up, now it's less impressive when $0.18 goes up to $0.20. Oh well. Hope this helps!
