Here's a good tip if you are not up to speed on scales:
Close your eyes and imagine what you would like to be able to play - then pick up the guitar and work each phrase and run out 'note by note'.

That's how I learned to play and it's still how I do things. Even when you learn scales and other bits of theory you can still incorporate this method. The great thing about doing things this way is that you will learn the fretboard largely by ear before applying theory - having a good ear is what separates good players from everyone else who simply rely on patterns and scale runs. Give it a go and try to do it for 30 mins per day - you should notice a huge jump in creativity which will encourage you to practice more. Hope that helps.
