Mission, vision and values are of prime importance for the business so you need to make sure that you have enough of business acumen and knowledge to write a good mission in life as well as business.
That mission in life is actually what will determine your guiding mantra in defining the vision of the company.
What is a vision – Vision is the long term guiding goal to which you have to achieve. This is not a long term goal.
Business goals are the measurable things that we need to have so that you reach the vision easily.
