With me it usually means I said something and then realized I'd probably get a ration of $h1+ for it.
My steps:
1- Decades of recreational substance use.
2- Get melody stuck in head for hours.
3- Hum melody into cell phone voice recorder.
4- Leave work early (priorities)
5- Scratch guitar/scat vocal track.
6- Gradually record all instruments over and over again trying to get "the take".
7- Going slower than expected so quit job (again priorities).
8- Keep tracking.... now my tight drum part is making the guitars sound loose.... time to re-track guitars.
9- Now tight guitars make drums sound loose, re-track drums.
10- Finally instrument performances as good as I can get them. Time for vox!
11- Track vox.
12- Listen back.
13- Wince.
14- Retrack vox.
15- Repeat steps 12-14 about 50 times.
16- Decide song would be better as instrumental.
17- Get on the mix, now that my ears are "primed" from tracking at deafening volumes for 12 hours.
18- Mix.
19- Listen.
20- Mix again.
21- Steps 19-20 a whole buncha times.
22- Post song to HR clinic, realizing it will most likely go viral when people bear witness to it's awesomeness.
23- Watch as song sails effortlessly off to the third page.
24- Get baked, decide next one's gonna be better.
25- Realize I don't have a job anymore.
26- Get new job.
27- Back to step 2!
