Systems not goals
You set yourself a fitness goal. This isn't the first time, you've set many in the past. Some of which you've made, some you're embarrassed to repeat because of how you never really got started. But you're going to go again, and in your head, you have an idea about what you could be capable of achieving; what you think will make you happy to say, "I reached that goal!" Regardless of what the goal is, run a marathon, complete an iron man, or tough mudder, bench press 80kg etc. it's going to take a while before you get there....
