The path to get the right type of motivation to play your guitar is to perform in front of people you know. Are you easy playing in front of people and relish every moment of it? Naturally it does not have to be a conventional event for you to play.
The way you could start with your guitar performance is to set up a reduced show in the setting of your own home. Your own family members could be the members of the audience. Several places can be created at house where you play your music and motivate pals and other family members to come up and play their own instruments as well. This of course needs some planning to prepare a domestic presentation and for your own preparation also.
But what happens if you detest the idea of performing? One way where you could practice with your guitar repertory is to continue playing in isolation and pretend that there are lots of individuals in front of you. If you want to help your imagination a bit you can put empty chairs in front of you representing the audience. In such artificial shows, you have to be true to yourself and play corresponding to what you had planned from start to finish, and if you make a mistake, what should you do? You would in all probability want to minimize the consequence of this mistake and just play on, so this is what you have to rehearse even in this comfortable setting. What will occur is that you create self confidence in your ability to handle errors and you will also find weaknesses you can improve upon in your guitar playing.
This playing could also be recorded and played again, for detecting mistakes, if any. The recording plan need not be made into something fantastic, as you have your cell phone and mp3/4 player, which can make these exercises very easy. Making a recording is similar to having a critic in the audience and listening to other players is also beneficial. You must have great dreams to be with the top rungs of guitar players and this can be done when you endlessly listen to others playing who are superior to you. You must work the same kind of love, which you would show in a performance when you rehearse you guitar pieces, or memorizing songs. As you learn your music you will also observe your position, posture and your tension level. The sense of joy and happiness that you experience during rehearse would spread to the audience when you play in front of the populace.
