How do you make Mondays more enjoyable?

I try to plan the week on Sunday evening to get a head start on Monday. It helps feel more organized and in control. And then I start the day with something I enjoy, such as a delicious breakfast or listening to my favorite music :)

By absolutely doing no work on a Sunday and not worrying about Monday. Earlier I used to think that starting up is a 7 day job. It is - if something breaks. But find a day for yourself when you are absolutely not thinking about your product. Sunday being Sunday may prove to be the best day to take a break. Your friends and family are free, and you can just spend quality time with them. When you wake up on a Monday, it just feels more refreshing and hence enjoyable. Imagine you went to this awesome party yesterday, and had a great time. The next day is just more enjoyable. The same applies here. Simple yet effective. :)

A new episode of The Last of Us was working for me in the last month... I need a new monday habit now

I just try to plan stuff on Sunday evenings like @kseniya_avtukhovich was saying. Takes any decision making off of my plate in the morning and makes it easier to get things finished. If you're finding your evenings more "Bleh" than you're wanting, try planning something you enjoy, like actually book some time out of your calendar to do whatever you would do on a Saturday. Cheers - hope this helps.

Mentally prepare yourself for the week ahead. I organise all my calls for the upcoming week on Fridays/Saturdays. Take it easy if you need to. Set your intention for the week.
