IT'S SUPPOSED TO BE HARD.
It's okay to be discouraged. It's not ok to quit. To know you want to quit, but to plant your flag and to keep inching closer to your dream, that's persistence.
Thomas Edison once explained that what comes first is the intuition, followed by a burst of energy, then the difficulties arise. What set him a part from all the other inventors was his tolerance for these difficulties, and the steady dedication towards solving them.
FACT: Your first attempts will seldom work. The same goes with the second and the third. It's going to take A LOT out of you. The good news is energy is an asset we can always find more of.
STOP LOOKING FOR AN EPIPHANY and start looking for weak points. Stop looking for angels and start looking for angles. Stop chasing money and start seeking knowledge.
Settle in for the long haul. You will eventually get there. And when people ask "How are things going?" The answer should be, "I am getting closer to living my dreams. And when setbacks arise I respond by working TWICE AS HARD because I am an Entrepreneur!" Make it a great day.
