...that little secret.

"The secret of getting ahead is getting started. The secret of getting started is breaking your complex overwhelming tasks into small manageable tasks, and starting on the first one."- Mark Twain.

Get started, break those complex tasks to manageable pieces and pick the one that looks easy to begin with.
Greatness is not forged on the back of laziness or doubts, it is propelled by man's resolve to stare right back into the abyss in that moment when it threatens to cripple you.
