There are an infinite number of possibilities of things that your life can become. If you are unsatisfied then it is in your hands to change things. This is what I always tell my husband, of course ther are things like kids and family that may prevent a big geographical change but other than that anything that one could be looking for can be looked for elsewhere. There can be so many other people that seem to lead much more fulfilling lives but in most cases the only thing they did differently is they went and got it.
External things (like corrupt politics, or strange unhealthy yet fully unavoidable food additives, or the endless filthying of our world or money being the foundation we build our silly actions around etc) I honestly believe that there IS more than that, yet it will never ever come to fruition.
Like they say, read a book, change a thought, move a muscle, but if nothing changes then nothing changes.
Atleast that's what I think.
