wow this guy on YOUTUBE is good with the guitar! makes me want to learn!
It ain't that hard BUT if you are really serious you have to take lessons and devote about 1 hour per day to practice. It took me about two years with a private instructor to get good at it. You have to truly love it, if not you can forget about it
Also, it is much more difficult for us adults. I have a friend that learned when he was a teen and he is a pro. So if you have kids, encourage them to take up a musical instrument. They will thank you later
To the OP question - learning bachat on guitar is tricky. I tried once and gave it up. You have to learn how to play with a thumb pick (which I am not too good at).
