hmm.... i'd say that depends on the implied context. does it mean that those with power will always get thier way? not at all. does it mean that one should just blindly use more force when they don't succeed? not at all. does it mean that one should just give up on everything instead then? nope.
personnally, i have 2 sides that argue over this from time to time my cynical side states: if someone else is trying to ruin your entire life, it is possible for them to succeed. my mad scientist side states: anything is possible if you how to do it! not knowing how is what makes it impossible, but knowing how makes it trivial! SCIENCE!!! and the catalyst i have for them both states: both are true, as nothing is truly immpossible, but other beings can increase the difficulty far beyond workably practical limits.
so the actual reason why there are so many people who find one or the other to be true is that they are both correct philosophies to live by. this has to do with the fact that while anything can be done, it needs suitable work and resources for success, and a lack makes for totally insurmountable difficulty, but an abundance makes for ease in accomplishment. this includes resources such as time,supplies,and even people. good example? is it possible for a human to fly? yes. could just one person build a jumbo air liner? no. could a whole crew united make it? yes. hence my ultimate motto: "in unity, there is strength." so all we really need to do to stand tall is stand together. such is the way of the neo-khala.
I think yes, but all depends on how you think about it, and how to deal with problems and frustration. You'll have nothing if you are a god at drawing but can't manage the hard situations.
personally I think when someone's enjoying what he/she does it's a great succed, cause it means it will do it with all the effort to get better at it and eventually can come with what he/she want to do.
