I go with the Ramones, I started writing songs because everyone else’s were too hard to play !

I also think that at times it is easy to get too bogged down in theory, if it sounds good to you then IMHO that is the only true yard stick to judge your own music by.

Unfortunately this approach can lead to getting stuck in a rut and for me, that is when a lesson or two can be very helpful.

Starting a band can also bring you along very quickly as inspiration can flood in from all directions as there is the opportunity to experiment and try out new things with the full ensemble behind you!

Hope this helps
