It takes me a week sometimes...
to even get started on something... to find my inspiration, form it into an idea... and make that idea concrete in my mind.
Once I've done that... I can make it happen... anything really, if the idea motivates me.
I don't think a week is a long time... but other people see someone sitting around for a week doing seemingly nothing productive... and that person is a time-wasting, money sucking loser who has no aim, no direction and no hope of accomplishing anything...
when I am met with someone like that... I can admit they are right...
I may not accomplish anything... for a week.(Edited 4 minutes later.)
