I am playing acoustic guitar from last 8 year still its petty difficult for me to plat the leads....I can only play major and minor chords..
What is it exactly you hope to accomplish on your acoustic? Do you want to play lead lines? Chordal accompaniment?
Jazz? Blues? Fingerstyle? Flatpicking?

Listen to a wide variety of acoustic pickers and decide what you want to do. Once you do that, then you can work on specific techniques to accomplish your goals.
