The other poster is correct regarding persistence.
Remember, talent is simply the result of years of honing your craft.
If you're right at the beginning, practice your basic chords and alternating your hand between the positions.
Learn these:
E, Em, D, Dm, G, A, Am
When you're comfortable with that, start to learn how to barre chords and learn:
B, F, etc
When you're comfortable with that, or if you're feeling brave, go to
www.ultimateguitar.com, pick a song you really like and have a go. Some songs will be far too technical for you at this juncture, but there are a lot of transcriptions of songs into basic chords.
When you're comfortable after that, try upping your game and start to learn some technique such as hammer-ons and pull-offs and pick harmonics.
Practice both with and without a pick. Grab a selection of thickness from your local guitar shop and see what you're comfortable with. If you're playing an acoustic, generally a thicker pick will be better for you. Similarly, you will find that you will have to press harder on the strings as the 'play' is a little higher than on electrics. It will hurt your hands for a while at the start but it does go away as your skin gets calloused and you begin to develop some muscle memory.
