I exercise for 35 minutes every morning and regularity is the key here. If you're not going to do it regularly, don't bother. First of all, exercise helps clear your mind and secondly, it keeps ailments such as back/shoulder pain at bay. Choose something that is manageable to you although I would recommend to aim for at least 30 minutes. I use Tracy Anderson's (Gwynnie's trainer, left) exercises videos. They're good for working those core muscles.
Bonus: you'll like what you see in the mirror!
When I worked in an office, lunchtime was the highlight of my day so it came as a surprise to me when I realised that mealtimes had suddenly become an inconvenience! I used to run downstairs and prepare something stodgy/heavy to quiet down that pesky rumbling sound in my stomach (do you mind? I'm busy writing the next blockbuster!). Few months in and I was virtually listless so now I make sure that I prepare nutritious meals. If it's trash, it's out!
Bonus: you'll have more energy and you'll feel a lot happier too.
No matter how lazy you feel/bad the weather is, make sure you go outside at least once a day. Besides getting your daily dose of Vitamin D, it'll just feel great to be outdoors.
Bonus: you can sunbathe anytime now, yeah!
And I'll allow networking as networking is not only vital if you're freelancing, but you'll also make great friends in the process. So yes, socialise, meet friends, go out until the sun comes up.
Bonus: unlike your friends in permanent employment, you get to sleep it off the next day!
Which bring us to sleep and yes, you'll need to sleep regularly and well (particularly if you've done a lot of the above). I tend to maintain normal working hours. I don't go to bed too late and I don't tend to wake up past 8.00 am.
Bonus: well, sleep just feels great.
