I felt the same way and bought a guitar 4 years ago.
I loaded up on DVD's and bought lessons on Garage Band (mac)... but I could never really master what they were showing, and without feedback, I never really trusted that I was doing the right thing. Eventually I got frustrated and quit.
Finally, last month, I called the local music school and signed up for 16 wks of lessons with a private instructor matched to my goals and musical taste. I learned more in the first half hour with an instructor, than I ever learned from hours of video lessons.
While my mind could write music or hear how music should be, I lacked the kinesthetic intelligence to create it and that was frustrating to no end. Unfortunately there are so many tedious, tactile movements to master before you can ever take it to the next level and instinctively play music. I have come to dread the first 10 minutes of class because I hate the monotonous plucking exercises.... but they help immensely. Watching online lessons, I learned a song to play, but I just mimicked what I was watching instead of feeling or knowing it (and there is a world of difference between imitation and creation).
Now it's the best part of my day. I wake up, practice guitar online for an hour to supplement what I am learning with an instructor. The entire time I smile like a fool because it feels so great to be doing something I had always wanted to do.
There are a billion other lessons I have learned in the process too, but that's another topic altogether.
However you decide to learn, good luck!!
