Maybe you've heard how good it is to switch from a single use coffee cup to a reusable one, but it's just hard to make the switch. What stands in your way of making this a habit? By identifying the challenges, you can begin to work through them to have better success in taking this action. Knowing the difference you are making, how does it make you feel?
The biggest hurdle to stop using disposable cups is while traveling - as there are simply no means of washing reusable cups properly when you're on the road for 2 weeks. Luckily, with Corona that's not such an issue anymore as I don't travel... I guess there's some advantage in anything :-)
