Success is not measured by money or fame. Instead, it can be measured by how disciplined and focused a person is, and also how much inner peace and contentment they find in their life. Discipline means setting yourself rules and following them, such as creating a timetable for when to focus on your work and when to take time off. Finding inner peace is less tangible but could include things like feeling happy and secure, having a sense of belonging, or feeling satisfied with your life.
