To achieve a goal you must plan how to make it happen. A goal without a plan remains just a goal – many people have ideas and dreams, which are never realised, because they’re not planned.
You cannot ‘do’ a goal but you can do the things that enable it to be achieved – usually several through a succession of several steps.
A good plan identifies causes and effects in achievable stages.
Even the most ambitious goals and plans are achievable when broken down and given a realistic time-frame, appropriate effort and focus.
