i dont think that i wanted either of them, cos with such povers you would be godlike and that's crapy
if you could control ppl minds you will use eventually that often and you wont be talking with ppl personalities but with your slaves (your mind creations), you wont be able to control your povers, cos if anybody will think different from you and you will have just a little disagree - you will chandge him, thats what i mean
think about that: if youre rich or get richer, step by step you think about yourself more important, you want different more valuable items and stuffs, you dont act like normal (its an example) and eventualy you become yourself's slave cos you are overloaded of you power and such things exist in the wold
as for time chandging....if you could chandge everything what happened and what will happen you will loose your joy of life it will be also boring (there is a movie named "Next" with david chadge i told that in case if youre interested in time control
)
