Noting the senses

Something changed yesterday. After waking up, my music taste had changed and I felt somewhat happy for no apparent reason. I'll try to use it for observing my habits and altering them. Thanks to whoever might've helped.

Also thanks to owltwelve for posting these videos again:

Had already forgotten about these methods. Tried the noting of the senses. Already the first couple of seconds woke me up. So simple and yet so effective.
