I have like 30 song ideas
Most people I know have tons of riffs, chord progressions and melodies; but it's a whole other story to take those riffs, progressions and ideas and turn them into songs
. The important thing in my mind, is to pick some and just finish a song. Come up with a structure, rhythm, melody ... and record it. If it's your first song, it will probably suck, but who cares? Finish it. I've written dozens of songs that are absolutely terrible, but they got me on the path to learning how to write. I don't regret any of those bad songs. If I never finished them because "they weren't good enough" I wouldn't have learned anything. I think being afraid to write a "bad" song is the #1 thing that keeps musicians from learning to write good songs. Everyone has cool riffs, just like "everyone" has cool ideas for video games and movies. Ideas are one thing, a finished piece is something entirely different.
The more I learn about music, the more I realize how much there is to learn. I could never get bored with this instrument. Try learning a different style (blues, country, bluegrass, jazz). Can you read music? If not, pick up Modern Method for Guitar, Vol 1 and dive in. Are you good at tapping, legato, alternate picking, finger picking, slide? If not, pick a new technique and start diving in. You'll never know what you might end up loving, and what might end up being incorporated into your own unique style. Pick up Ted Greene's "Chord Chemistry" and dive in. Pick up "The Advancing Guitarist" and flip to a random page. Lots of good inspiration in those books. How is your ear? Pick a song (or solo) that's at your technical ability level, and learn it completely by ear - chords, melody, harmony parts.
I think everyone - myself included - goes through phases. At some point if you really love the guitar you'll come back. Some times stepping away for a bit is actually productive, too, because it gives you some perspective, it can give you new creative ideas, and it can renew your faith and love in the instrument.
