The Roots of My Demotivation. + Weekly updates?

If you're struggling with demotivation with your projects too, this may help. :/ Maybe. Depends.
lol the title of this Journal sounds like the name for a song.

SO anyways, upon speaking with my sister about my lack of progress on a lot of things (songs, art, Memories of the Future... ESPECIALLY MotF...), I learned something from her that I really wish I'd known sooner. I kind of noticed it too, but I didn't really realize it was actually happening. I thought it was a coincidence.

Apparently, announcing publicly that you are going to do something (i.e., "I'm going to write a new song soon!" or, "I'm going to draw a series of fanart posters!", ..."I'm going to work on MotF!" //shot, etc.,), will actually give you the same satisfaction as ACTUALLY doing it. Thus, demotivating you from ACTUALLY doing it.
I'd always noticed that whenever I said I was going to do something, I'd never  really do it, but when I didn't say anything about it, it got done lickety-split. o3o ...usually;;;
I didn't realise it was actually something psychological. I just thought it was like, a coincedence or something. :/

So uh... yeah, no moure Journals telling you what I'm doing next. :/ I would frequently touch on those things in older Journals. Won't be doing that anymore.

However, (going kind of against what I just said) I was thinking I'd do a "weekly update" thing or maybe "biweekly updates", where every week (or every two weeks) I'd update, telling you guys what I've been up to and what I've made progress on. I wouldn't say anything like, "Hey I plan to start this soon...", it'd just be what I'd been doing and how much progress I'd made. Hopefully having a weekly update thing would help me to want to work on things so that I wouldn't be updating like, "yeah... no progress... ehehehe;;; //shame."
Though I don't know where I'd put it. Here, make a tumblr, Twitter, or a FaceBook page... I think I'd prefer it be here, but I don't wanna spam you guys with Journals. =/ Maybe I'd just have it be one Journal, then I'd clear last week's progress and replace it with new progress every week. idk.
What do you think?
