Follow your value system. You will not regret it. Examine your talents, your attributes and your affinities and develop an idea for entering a business that you would enjoy.
Our existence and our mental universe are driven by factors that we as individuals inherit through the gene pool, as enhanced by our experiences in life. In short we are most at peace when we are in sync with the personal value system that has evolved as a result of the above factors and when we are permitted to pursue our values in our personal and professional endeavors.
If we cannot achieve that harmony we will seek change.
Find the niche that satisfies the above and you will find the long term spark for success you are seeking.
