When I woke up at 3 AM and can't go back to sleep, I find myself hooked on watching YouTube videos preferably, news and music. I watch old movies of Charlie Chaplin and Shirley Temple too. If you haven't seen their movies yet; I dare you to watch and you'll comeback here and thank me for sure.
Lately, I was watching guitar plucking and was deeply in-love with the skills of many YouTube users. They could be famous you know if they pursue their talent and skills. I also watch some videos of those who played harmonica and they're really good. I like Bob Dylan's harmonica solo. I have no skills in playing harmonica but; if you have the talent, go for it. Make sure to check out lee oskar at guitar center if you are looking for instruments and gadgets. Tutorials for any musical instruments are in YouTube too so; get your instrument and start learning.
