Every new thing comes from the destruction of something old.
New, better habits must come at the expense of old bad ones.
So if you are having trouble visualizing yourself achieving a considerable goal, don’t stress about it. Try a different perspective.
You, as you are, will not be the one achieving that goal. You, as you are, would have already achieved that goal if you were fit to. But you’re not.
The person you will become, through great effort and adversity, will be the one achieving that goal. That person is not you, as you are. That person is you, as you will be.
It will be hard, frustrating, and often painful. But if it’s important to you, it will be worth it.
Focus on making the right changes, on letting go of the unnecessary or detrimental habits, and you will often find that the change you seek will grow in their absence.
