Just a couple of observations here, how have you gone about planning this trip of a lifetime? There are a number of books easily available that you could have consulted before committing yourself to buying any type of airline tickets.
I know you have stated that for your first five days will cost you £91 – but what about your meals? Given that this is January and European weather is somewhat unstable at this time of the year, you will need to eat, plus keep warm and travel with winter clothing which all adds up in the long run. On top of this you have only paid hotels deposits; accommodation is not cheap in Paris.
With a bit of planning it would have made more sense to have flown direct to SE Asia, especially in January, rather than toiling around expensive European cities in the middle of winter.
Next, have you actually spoken to the American Embassy concerning your Police caution, which is not exactly the same as having a criminal record? Speak to the Americans first, not your best mate or someone down the pub that is some travel expert because he lived in Canada forty years ago. With a caution you have accepted responsibility for doing something wrong, and the police are taking no further action. You have not spent 25 years in prison for trying to destroy the country or rob the bank of England. Speak direct with the American Embassy.
Your initial question about how can you travel the world on a budget, let’s be honest £10K is a significant amount of money, for a short trip, but not a fortune in these days for a world tour. However, you need to think strategically and creatively about what you can do with your budget, starting off in Europe in winter is the easiest way to burn through all your money and not even get too see much of Europe, let alone the world. On your current plans you would last just three or four months not a year.
I take it you are planning to leave next January , therfore I am not sure why you are panicking to purchase travel tickets for ten months away. I suggest you go to your nearest library and take out some travel guides and get reading & planning.
My advice, forget about the tickets you have purchased, deposits paid and start over again. There are more things I could offer you but suggest you plan this out carefully then come back with further questions.

Số gam nước lọc để có 4% lượng đường là:
3,6 x 5 : 100 : 4 x 100 = 4,5 (kg)
Số gam nước lọc cần thêm là;
4,5 - 3,6 = 0,9 (kg)
Đổi 0,9 kg = 900 gam

a) \(x^2+2x+1\)
\(=\left(x+1\right)^2\)
b) \(9-24x+16x^2\)
\(=\left(3-4x\right)^2\)
c) \(4x^2+\dfrac{1}{4}+2x\)
\(=4x^2+2x+\dfrac{1}{4}\)
\(=\left(2x+\dfrac{1}{2}\right)^2\)

Siêu tốc tổng quát: \(\frac{1}{n.\left(n+1\right)}=\frac{1}{n}-\frac{1}{n+1}\)áp vào
\(A=\frac{1}{1}-\frac{1}{14}=1-\frac{1}{14}\)

A=(2-1)/1.2+(3-2)/2.3+...+(14-13)/13.14
A=1-1/2+1/2-1/3+...+1/13-1/14
A=1-1/14=13/14
