The Oxford met cd is the very one I am currently using! I heartliy recommend it as it has really helped me on visualising the information,something that text simply cant do if like me you dont have a very imaginative mind.
As for tips to stay focus,My motivation is my desire to get the hell out of my current job,not because I hate it ,as it has given me the oppurunity to go for my dream job but it is not what I want to do for the rest of my days,all I want to do is fly aircraft! Having a job that you love and are proud to do is my desire and that keeps me on track,
just dont go to Florida have a nice time like I did and come back all depressed about the state of the country you live in!! But that is another topic
good luck to us all
