hey there, I just thought I'd offer a little advice, I've taught guitar, often as a favour, sometimes for money and it's a very rewarding experience. I would go with everyone else and check into lessons, guitar teachers usually will help you improve in areas you are interested in, and wont force you to play music you dont want to. I would also advise learning music theory as well, that way you'll be able to understand what a lot of the guys in here are talking about when they mention diatonic scales, ionian modes and such.
You may also find guitar addictive, I know I did, when I first started playing, I learned the A, E and D chords and i would play the 12 bar blues to the point where my dad threatened to throw my guitar on the fire if I didnt shut up. I had blisters all over my fingers and they hurt like hell, but the next day I was playing again. It's like learning a new language and learning a new trade all rolled into one. When you start to get good, you'll realise how much fun it is, and carry on!
Dont look at it as work, that's the first step in becoming more proficient!
