• Meet regularly with employees to review projects, track organizational goals and objectives, etc.
  
• Remember to not only celebrate your success but also carefully examine it to determine how it came to fruition.
  
• Continually innovate and experiment - even when it's not broken.
  
• Realize that replication is not actual learning so do your best to LEARN daily in an effort to improve and grow your business.
  
• Focus on any failures and learn from your mistakes to prevent them from reoccurring.
  
• Make sure that good leadership is in place that promotes a positive organizational culture built for continual growth and learning.
