hi guys, how do you write songs,riffs or whatever?
for example i have 2 ways

1) its the rarely happening one,and its like i get a sound in my mind,wich grows and grows until i have to compulsively play it,it used to happen when i was a kiddo but now past the 25 to now 33 it happens rarely

2) i keep noodling and noodling and noooooooooooooooodling until something wich capture my attention happens and i try to elaborate it,usually it ends with nothing more than a good riff.

do you have any ritual or tips wich helps you stimulate your creativity? once you get a good riff how you use to elaborate it into a full tune?
