If you can’t quantify your goal, how can you assess your progress or when you’ve achieved it?

Your final goal - and the intermediate steps - must be measurable by such things as time, kilos/pounds, centimetres/inches, dress/trouser size, minutes/seconds, etc. or whatever scale is relevant and appropriate.

Part 1: Goals must be realistic and achievable
Part 2: Goals must be specific and personal to you
Part 3: Goals must be measurable
Part 4: Goals must have a time frame
Part 5: Goals must be written down
