“I have a really big goal and I really want it to happen. So I always go to work on it, then it seems so big so I eventually become unmotivated and stop completely.” I know this is very simplified but does this sound like you? Goals need to be made with an end vision, and a plan of action which breaks the goals down into achievable steps. The vision must have a very clear picture of how you stand to benefit from the achieving of the goal, as well as steps which are attainable.
Break down big goals. It’s great to have them, it’s great to want big things, but without the vision and the proper steps, you’re heading for a place where you’ll stop.
