For one, we are more alike than not and, if I can think of the problem, then you can think of an answer. Expecting success breeds success. Any situation may be used as an opportunity for strife or for goodness. If I live in a world where I trust reasonably and enjoy myself, all will be well. However, I must think of all time as within my grasp.
Happiness eludes the time-bound and the earthbound.
Always treat the world as you wish it to be. We say that humans can choose how they act and who they are while animals cannot. Lacking consciousness, it is presumed that animals are natural, by necessity and cannot be other than they are. This is untrue. Most animals choose to live in the world as they see it.
