Back at university I was part of a study group, where we'd talk about our motivational issues and give each other tips on how to learn more effectively/getting more out of our time at uni in general.
The focus of these group sessions lay on making a sensible schedule for the current week (we met on Mondays) and trying to stick to that schedule. In order to do that we were given some timetable templates and highlighters. We dedicated certain colours to certain activities (i.e. green for lectures, red for self study, pink for exercise...) and filled out our timetables like that. To control how much we got done, each day had two columns: for the activities we planned and the ones we actually did in the end.

While studying there didn't work out in the end, during my time there this study group helped me greatly in getting things done and actually for once in my life getting a decent routine into my everyday life. Now, while taking a break from my studies due to mental issues, I am missing this daily routine once more, stay up for way too long and get up too late.
My psychiatrist recommended me to try to get used to a daily rhythm once more. Hence, here's my timetable template, similar to the ones we used to get handed out in our study groups. I figured it could help people who struggle with sticking to a routine as well.
