Most start ups begin with an objective of building a palace for the queen at home. However the start is stressful and most successful business people have a little time for family. At such times a supportive partner is the strongest support system. If the partner is not supportive, its not worth risking your life building a castle.
My people would have asked me to visit the Psychiatric, if they hadn't seen the success of my earlier Startup. But Frankly speaking, sometimes when you see what your family goes through, it doesn't seem worth the trouble. However, the lure of rewards & recognition and sometimes with no other alternative (Entrepreneurship is an Addiction) we feel like finishing it all in a hurry.
