Like everyone says do what you know is right nobody can tell you what you should do.
I wanted to go travelling as soon as i finished high school but decided to go straight ot university i lasted about 2 months before i decided i needed a break from study. my intentions were...to be honest i didnt know. i figured i could work and save money to go travelling but being unqualified i ended up doing manual labour jobs and not earning much money so after 1.5 years i was back in University and ready to study. University was the greatest thing i have ever done i enjoyed the social aspect and the books side of things (I did a bach of Exercise science and then a bach of Education) the years i spent at university i grew up so much whilst at the same time partied and learnt so much. The last year was extremely hard though because the travel bug was biting hard many of my friends were doing it at that stage but i was detemined to finish uni.
I finally did finish uni July 2007 but because i was living/partying above my means the travel had to wait until i had paid off the credit card and saved some cash. So i entered a year and a half of work life to a certain extent it felt like my life was on hold just waiting to finally go travelling but by the end of this time i loved my job so much that again i had doubts on whether i should leave. Anyway August 08 i finally did it 2.5 months backpacking europe and now i'm living in London saving for a 3 month trip over next summer.
Im now old enough to enjoy the travel and im glad i did it this way i also have a job that is very easy to get work because im qualified and i can save for the next trip a lot quicker.
I suppose if you have dreams and your determined you will chase them no matter what. for me the first time i dropped out of uni everyone said i was stupid that i would never go back i did, when i left my job back home everyone said i was stupid because i had landed the perfect job and was going places but now here i am doing what i want.
what im saying is you and only you know which is the best order to do things, happy travelling/studying whichever one you choose you won't regret it if you are true to yourself
