Yeah symphonius, for a couple years there I think I could relate to what you're saying. Like theres not much to you, so theres not much to what you have to say. I can assure you however, that everyone is an individual and absolutely does have something to say and contribute, you just have to re-connect with that deep part of yourself ("Your inspiration IS within you" quote that HBS gave for example). Its only now that I'm beginning to get a hang of this. Before, I felt like I was just stumbling around taking whatever ended up naturally and randomly inspiring me in my day to day life, and usually those things were good for a decent song or two, but it was so few and far between. It didn't consistently have that powerful emotional connection to myself and others like you are talking about, though from a musical construction standpoint it was good.
I've really made it a point to be intentional and decisive about getting inspired, no matter what it takes. I am not picky. I'll take it anywhere I can. And honestly, in the process I have been learning a lot about myself. Another major thing that helped make the whole process a lot more simple was thinking to myself, "when I was younger, even before I started getting serious about this music stuff, what inspired me? What brought me to life and made me light up?". A few more things just popped into my head: being outdoors; painting/drawing and looking at art, cooking, reading plays and going to theatre performances and symphonies, concerts etc... also, I think a major part of your inspiration is this willingness one must have to go to those places that scare us, make us sad, etc... whether its talking to that girl you keep wanting to, or doing that thing you've always been afraid to, or rekindling that relationship with that important person in your life, working through deep issues, etc... That type of stuff absolutely gives rise to emotional opportunites to write about. THAT kind of stuff, people can absolutely relate to.
I think the key is that whenever you are doing these things, don't even think about your songs. Do them because you are trying to connect with yourself, and its that connecting with yourself that gives birth to your songs. And its about way more than the music here. Trying to reconnect with myself, and the city and the people around me has done wonders for my individuality and happiness beyond just a songwriting stand-point. And if you keep that up for a few weeks, before you know it you'll see something and be like "holy crap, I could write an awesome song about this". And you'll just start singing, and the ideas will begin to flow, and then your craft and technique will take over, and before you know it, everything will have paid off.
(Side note, if you check out my latest song "Lonely Love" on the lyrics critique section of the forum, this is the first song I have written as a result of everything I am talking about. I had been downtown about 3 nights in a row, and doing other things to catch inspiration and I noticed one thing every night: multiple beautiful women, out walking- alone... and the hook just fell into my brain "Why do you have to be such a lonely love?". I'm really pleased with it. ::selfish plug:: haha)
It sounds like you know whats going on man, and you're on your way- I'm stoked for that
