The most common characteristic we find in successful people is consistency.. they just didn't stop..they took one idea and manifested it in reality with consistent efforts..
They got many barriers,many people suggested them to just stop and do something better.
Many people just laughed at their idea..and declared them as fool.
Winners always know what they are doing, they are always consistent in their efforts..
Just decide and follow your path ..analyse the problem and learn from your mistakes......this should be consistent....
