The Underground Ukulele Railroad

The overall simplicity of the ukulele makes it challenging to judge my progress with it. I have hardly touched finger picking, which in all honesty, can be as difficult as anything depending on its complexity. I know that any pop song or rock using chords and a standard progression is nothing difficult if I only need to strum, however once it becomes necessary to pluck intricate melodies along with strumming is where my capabilities end. This is where the problem of not taking lessons from a private teacher becomes apparent. I do not know the direction I should be taking myself. I have recently found  a site called "Ukulele Underground" with almost 100 lessons on songs of varying difficulties. I will most definitely be learning my next song from their library of videos.
