1) Build a meaningful career to have a meaningful life :
A large number of people go to work each day to a job they don't like to work for. The harmful feelings pervade through their entire life, putting a negative cloud over the family, friends and many of their other activities. They may lack the ability to change, and may be afraid of leaving the surety of a paycheck, or have hundred justifications for them to be so dissatisfied and stay at their job.
2) Analyze Yourself :
Ask yourself -- What actually matters to me? What are my likes and dislikes? What problems I am having and how can I fix it? What is my passion? What is my secret desire? What do I want to achieve in my life?
3) Utilize your individual genius and talent :
Every person is born with a unique set of natural talent and abilities. You can have a natural flair or talent for various activities, such as - management, creating, writing, research, training others, drawing etc. & you can do these activities very easily and with interest. True happiness and joy comes from within by combining your natural talents and interests, growing & excelling in them, and working in a field, job or industry, which you have a passionate interest in.
