Hi Lieven,
James is 100% right. Writing songs is a disipline that needs practice and patience just like learning to play the guitar. All of us write some good stuff, some mediocre ones and some darn awful ones. OK Jeff and James produce a great number of songs but I would like to bet that they both have a lot of unfinished ones and others that they are not happy with. They have been writing for a long time and it is easier for them than it is for most of us but it is NOT a competition, it is supposed to be fun.
Yes it takes time, but so do most things that are worthwhile.
Why do you need to use less difficult chords? If the music calls for an obscure chord then so be it.
None of us are competing and often what one person does gives an idea or inspiration to another.
Maybe what you need to do is to find one that you like and spend time to work on it to get it as good as you can before posting it. Or post it for opinion and then revise it if neccessary. It certainly helps if you can record it so you can listen to it critically and see if it can be improved.
I will let you into a little secret here but don't let anyone else know. Nearly every song that I have put on Chordie I have sent to my two critics first, my ex-wife, Sue and Helena (Old Doll) and I get their opinions before I post it.
Another idea is if it is the lyrics that are a problem and you are happier writing the music why not ask someone to write lyrics for you. I have on a couple of occasions taken someone's poem and put music to it, that can be fun too.
And if I were closer I would be bullying you into using your Boss BR 600 and recording your stuff.
Take care,
Roger
