As Roy Castle said "dedication is what you need". If you want to do it badly enough you will find time.
If you work 9-5 Mon to Friday its tough. I am lucky to work shifts so my days off are for studying (did struggle today though after some numskul broke into my car at 2:30am last night). You do need to take your mind of your studies now and then, its important to get a few beers down he neck now and then to retain your sanity - its no good having all your licenses if you've gone mad in the process!
