Welcome, Junas. Best advice I can give is to take things nice and slow as you will continue to learn as long as you play a guitar - YEARS!-Do not worry about not being able to play a song until you have learned the ability to form your chords correctly, change betewwn cords cleanly and learned the fingerings for scales. Learn the open chords 1st. - A, C, D, E and G - these chords are all you will ever need to play thousands of songs. Learn the 7 chords - A7, C7, D7, E7 and G7. (B7 is also an easy chord to learn) Learn the minor chords - Am, Bm, Dm, Em (these are easy). Learn the chord progressions - again there are thousands of songs the need only 2 or 3 chords to play. After you have these open chords down you can begin learning some scales - Major Penatonic Scale and the Minor Pentatonic Scales will be a good way to start.
Again, take things nice and slow - learn the techinque - remember you gotta crawl before you can walk and walk before you can run.
