How many times have you sat at your desk or on the tube and wished you weren't there?
Even if you have the best job in the world, there's a chance that you've dreamt of sacking it all in and travelling the world.
We watched this talk from adventurer Alastair Humphreys about his journey around the world on a bike (as someone who'd barely cycled before!) - and it got us really inspired.

You Don't Need That Much Gear
There's a common misconception that you need lots of gear to travel around the world. It's just not true.
The trick is packing light. Get rid of those extra pair of shorts that you've slotted in "just in case". You're not going to need an ice axe if you are in the middle of India.
All you need is a bike, a tent, a water bottle and rucksack.
(Obviously, other things are useful too. Tom Allen has put together this very handy list of things you could consider before setting off.)
It's Very Eco-Friendly
What could be more eco-friendly than travelling by bike?
Flying is probably the worse impact we have on the environment. A round trip from Europe to New York creates three tonnes of carbon dioxide per person, according to the New York Times.
By cycling, you are not producing any carbon emissions. You're just using your own human-power (and sweat) to pedal your way across continents. Mother Nature will thank you.
Relatively speaking, if you have a bike and you are fit to pedal, that's pretty much all you need.
There might be ferry costs along the way. You might get a puncture. But really? The costs are minimal.
If you've got a tent strapped to your bike, then bonus - accommodation is free too! So don't use not having any money as an excuse.
If you want to be a bit more practical about it (I don't blame you) then check out this article from Tim Moss. He breaks down exactly how much the average long-distance cyclist will spend.
You'll Meet Some Amazing People Along The Way
While travelling you will inevitably meet a whole host of interesting characters along the way, but on a bike, even more so.
From sitting on trains to encounters on the side of the road, you will inevitably attract a lot of questions about where you are going and why you are doing it on a bike.
Twitter is an amazing way to connect with fellow cyclists on the road. There's a whole group called WOW (Women On Wheels) which aims to connect women cycling solo around the world.
You'll Get Seriously Fit
If you're taking on a 6,000+ miles by pedal power, you will get seriously fit.
Those flabby stomach and soft thighs will be turned into hardened muscles of steel after days on your saddle.
Alastair Humphreys certainly wasn't a hardened cyclist when he started his journey around the world. Look where he managed to get to!
You Get To See The Landscape Properly
When you are in a car or on the train, all you see is the landscape whizzing past the window. You don't get to experience all of those places in between.
Sometimes these can be the most interesting places of all - with real people and cultures you otherwise would have missed.
All hail the slow pace of the bicycle!
It Will Be Really Hard, But You Won't Regret It
Let's not beat around the bush here: it will be really, really hard.
You're cycling around the world for pete's sake. No one said it would be a stroll in the park.
You will have blisters on your hands, a sore bum and you will get sick of living out of a backpack. But we can pretty much guarantee you won't regret it.
Maybe You Won't Ever Come Back?
Once you start, who says you have to stop?
Some people might not like the prospect of cycling away from their home, job and everyone they love - and that is completely understandable.
However, for some, it might just be the perfect excuse to keep going. If so, good on you, girl!
