What Milestones did Lucy achieve in her lifetime?
please help me ​

Life is full of milestones, just like projects. When planning a project, you must define the tasks that lead you from beginning to end, and you will inevitably want to mark key dates along the way.

Milestones allow you and your team to stay on track for the end goal, and they are also useful as a leader in evaluating your project whether or not it complies with the schedule.

For example, when planning to open a restaurant:

STEP 1: Moral commitment and decision.

STEP 2: Develop the concept.

STEP 3: Conduct a Market Study

STEP 4: Choose your location and your local.

STEP 5: Write your Business Plan.

STEP 6: Choose the legal status.

STEP 7: Take the administrative steps.

...

Other steps can follow after the opening of the restaurant as to achieve a certain turnover or enlarge the restaurant.
