I tend to make notes habitually, so I usually use 'sticky notes'. In fact, I face amounts of colorful waste every day as I create and erase. To replace sticky notes, I developed a website myself. This site saves the notes that I write in the internet cache, allowing me to check them anytime. There's also a feature which notes disappear like a sticky post-it when clicked. Now, my trash bin may not be colorful, using the web. https://yirang.neocities.org/Sticky-notes/
