Buy some flowers 
Recently every Sunday evening I have been on a trip to Lidl to buy a bunch of flowers. Then I set them up in a vase and it will always make me smile when I come down to my office and I can smell the fresh flowers and puts me in a good mood.

Plan my week
I like to be organised and plan out my week effectively. If I have work deadlines or places that I have to be I find it a lot easier to mark it all down on my weekly planner. Then my week is all planned out and I can ensure that I don't miss any deadlines and also that I can prioritise my work as to manage my time most effectively.

Make a list for Monday
Similar to planning my week, but once I have done that I will make a more detailed plan for Monday so that I can easily see what needs doing and it motivates me as I see my list getting smaller throughout the day.

Tidy up
I always try, especially when I am at uni and working, living and sleeping from the same room it always ends up (no matter how hard I try) getting really messy. I have learnt from my first year that whenever my room is messy and untidy it really demotivates me to work. By doing a quick and speedy clean around wiping up surfaces it makes it a lot easier on a Monday morning to get up at the start the day in clean surroundings.

Have a pamper session
I always have a pamper on Sunday and take it as a time to do skincare such as face-masks, along with pore strips, and having a bath. I also use Sunday evenings as a time to sit and repaint my nails to give them a bit of a refresh ready for the upcoming week.

Healthy breakfast
I also make sure I have all the ingredients to make a healthy breakfast, whether that would be a giant bowl of fruit, pancakes with fresh berries or avocado and eggs on toast. I also always make sure that I have fresh juice for my breakfast.
