Being proactive and cool

In personal and professional life, everyone has some primary responsibilities which can be done only by self. When we do not execute the primary responsibility on time; the consequence may be more stress or pain. Also by nature, any delayed response will consume more time and energy.For example, 

As an individual, if you are not spending time proactively on taking care of your health, any way you need to spend time when you get sick.

As a business head, If you are not spending time proactively on planning your customer orders delivery at the beginning of the month, any way you have to spend at the end of the month in firefighting mode which more stressful.

As a leader, If you are not spending time with your team on developing, mentoring and teaching the skills, any way you need to spend time when they make costly mistakes in their execution.

As a parent, If you are not spending time with your kids during  childhood on values development, any way you need to spend time in future when they slip on the life values which is more pain

The point is that proactiveness is required at least on your prime responsibilities. Else, any reactive time spending would affect the quality of life. Hence, be aware of your prime responsibility and be proactive!
