In your mind’s eye, clearly picture what your preferred future looks like if your goal is reached. It must be specific and it must be compelling.
Then, make some boxes that lead toward that vision, and some boxes that lead away from that vision. In the boxes that lead toward it, begin writing tangible actions within your control that get you closer to your goal. Make them specific, measurable, attainable, relevant, and time-dated (SMART). In the boxes leading away from your goal, begin writing tangible actions that sabotage yourself from attaining your goals.
Then begin living out your best version of yourself, and building up boundaries against the less than best version of you.
