I agree with the earlier posts and echo their sentiments as well. I`ll just add my two cents.

Being a goal oriented person, I have to fight the urge to try to put pressure on myself to achieve a certain level of competence by a certain date or finish a tutorial by a self imposed deadline. Learning guitar or any musical instrument is a journey with many ups and downs and side trips along the way. Enjoy the journey and embrace the challenge. There`s enough pressure in life ( especially nowadays!) without placing more on yourself while playing guitar. It`s a bit like putting pressure on yourself to try to fall asleep during a restless night; it just won`t happen. Just enjoy playing and know that every hour you spend playing is one hour closer to the goal. That makes achieving it all the more sweeter and satisfying!
