Hi  tattat,

To get to my work I travel by the tube at times. The journey is and hour and a half long. In order to pass time I like a lot of people fiddle with my smart phone. In doing so I discovered an app called Googel Primer (a learning app) on the Google Play Store. This app has a whole load of lessons on Business Plans and many other things. 

If you have the time it would not be a bad idea to download this on to your mobile. It could give you some very useful tips on how to Plan your business. Best of Luck.
