What was the motivation that brought you where you are today? Taking a step back, in time and conscience, is necessary for you to know you are still on the right (e.g. wished for) track.
Circumstances change, it’s a fact of life. How far have you gone from what you initially wished for? If you find yourself too far away from what you really want, it’s time to stop. Once more. Look back, take one, two, three… or as many steps back as you need. Put yourself back on the track. Don’t compromize too easily. Not if you’re up for a life long change. Easier said than done, but well, it’s for sure worth.
