The best camera is the one which is in your hand. Not the one sitting on a desk. If its not running than that thing if of no use. Use the thing which are around you to make more things which will help you.
Trying to do many thing at once is really hard.
I try to make myself busy by doing something when i feel like bored. I also have this bad thing that when i go lazy i don't become lazy or sloth like for a moment or two. But, instead that thing continues building up slowly and it explodes and then when i am out of the lazy circle. I do all the things at a very fast pace. Sometimes i cant really understand what's happening around me.
