Indiscipline, I can't do spirit, laziness, the fear of taking risks, procrastination, ones self, environment, too much flexibility, and the likes maybe an obstacle for not pursuing one's dreams but for me I have come to the realisation that we often times neglect the God factor because it's stated in the NIV Bilbe that "Many are the plans in a man's heart, but it is the LORD's purpose that prevails. (Proverbs 19:21). And there's also an adage that says "do your best and God will do the rest" so not doing my best to overcome those obstacles and neglecting the God factor is my reason for not pursuing my dreams.
