The first thing that you need to do is to learn to play a guitar. You can obviously skip this step if you are already good with the instrument. However, if you recently became interested in it, there is a very good chance that you will have to put in a lot of effort to learn it. Look for a guitar school in your area and get yourself registered there. Remember to purchase a guitar first though. There is no need to spend big money on your first guitar though. Just go for something that is decent enough. Avoid purchasing a guitar of poor quality as well, since it will keep you from learning the instrument.
Once you have bought a guitar and registered yourself in a guitar school, make sure you attend the classes regularly. Learning anything new requires a serious commitment. You cannot expect yourself to learn the guitar overnight, so remain patient. Remember to pay special attention to the lessons relating to reading guitar tabs. Do not try to look for short-cuts, as that will maim the learning process. Take it slow and steady. Do not lose hope if you do not see any apparent difference in your guitar playing skills in a week or two. Keep trying hard and it will not be long before you start noticing the difference
