I worked in a job I really loved a few years ago, then my friend decided that she wanted to go travelling for 12 months. I really wasnt interested, I wanted to stay at my job ! But after talking it through with work colleagues and family, I decided to go, big step for someone who wanted to buy a house, new car etc.
I was 24 at the time, and decided, lifes too short, go out and do it !!!
Anyway, cut a long story very short, I actually travelled for 18 months, the majority of that time was working and travelling around Australia. And can certainly say, it was the best time of my life.
I have never looked back and regretted any moment of it. I still look back at photos to this day and can't believe that I have been to so many places.
Basically, what I am trying to say is that, you have the money, your still young, get out there and see the world, if you dont do it now, you will regret it.
think of all the job experiences you will benefit from, I did so much agency work, my CV was 6 pages long when i came back.!
You can still buy your house and still have a career when you get back, I did !!! Ive got a gorgeous house, car etc. there is no age limit to this ! but seeing the world while your still in your early 20s is a must - trust me on this !!!!
Good Luck !!!!
