People who believe they'll
if they go and live somewhere else
learn it doesn't work that way.
Wherever you go, you
take yourself with you.
Whatever it is that is making you unhappy will be with you wherever you go.
If you decide that you can no longer take your current situation and that you deserve to be happy .... the further from here the better. Your first thought may be that you need to start again somewhere else on this planet.
Sometimes a change of scenery is all that is required to kickstart the next phase of your journey, but it is not a way to escape from life. Running to a far off destination will never be more than a temporary fix, never a solution. All of your problems will just go with you.
"Peace comes from within. Do not seek without" Buddha
Once you understand that the next town, the next partner, the next job can never be the answer, you finally see that you need to look in the mirror. Everything stems from you, this is your show, you call the shots. You just need to make a conscious decision to be happy. If you work on that, it will make no difference where you are or who you are with, you will be happy.
