An improved working

 
  This work by Ben and spellhawk; To feel an think about of "aetherical energy", which is energy that is of all the elements that can be used as of thought, that it does get manifested by ether, an then put it out there by thinking its there and feeling it form by imagination, to manipulate it more easily. As if, a free flowing force of aether is as any energy in particle form. Then slow time and do this by feeling time slow as if if a clock in your head that you imagine a hand (the minute and seconds hand) slow down to what timing you want. Or slow down time using a watch as the focal point for the effect by thinking it slowed and it expands out. To think it affected the entire area might work as the clock doesn't run slow, but you can use its battery and the fact that it keeps time as a source to affect time. 

  This is to make improvement in work in an area, but you can also affect only yourself by thinking it, what you did, does. As then after, you feel or think it necessary, speed up time by thinking time moves normal again while thinking of your watch batteries or thinking of the clock in your head and the minute and seconds hand speeding up to what it was as you allow it to expand out and effect the area. If you speed up time, you're speeding it up for yourself and everyone else, too. You have to increase or decrease the speed of outside time, while keeping their mental clocks running at the normal speeds. As it has something to do with the aether, for aether can effect time in a major way.
