No one likes a down daddy, manic mummy, or scary sibling, so consider taking a few moments to a whole day of 'me time' - it's essential for keeping you sane, let alone happy.
With busy schedules, and work/family commitments being the focus of your attention, it's easy to forget about yourself. Think about your life as a big pie, with slices of everything you need to do: career, children, housework. Taking a slice out for yourself doesn't always seem feasible. Many consider 'me time' a selfish phrase, coined by those who have a spare minute or hour to do whatever they like. 'Me time' is in fact a necessary component for keeping you happy, and functioning.
Employers don't appreciate it when staff are erratic, pressured, or stressed, so if the looming deadline, target, or task seems like too big a burden you need to remove yourself from the situation, mentally, and if possible, pyshically and take a time out. Checking in with yourself and giving your mind a few minutes to zone out, and escape will help to sharpen your focus, and be on your 'A' game even more.
Studies have shown that a mere thirty minutes of reading a book, stretching your legs, getting outdoors, or even painting your nails improves your mood, and helps your mind re-evaluate what's important.
Acknowledging that your personal needs are just as important as those in your work/home life is key for keeping you going.
I frequently indulge in nail-painting, even if it's at my desk, it keeps me happy and makes my hands look 'nice'. It sounds silly but it's my five minutes of 'me time' in the office, even if I do have a deadline, I can tick the mental box of 'need to paint nails', off my mental checklist and start prioritising.
Escaping into a book on the train is also how I like to relax. On the way to a meeting, or an important ten minute tram ride becomes a lot less daunting once I've had my ten minutes of escapism, and I'm certainly happier as I float off the tram, with a little bit of a story still in my head. So, drop the guilt and start running that bath.
