Persevere

Permanence, perseverance and persistence in spite of all obstacles, discouragement, and impossibility: It is this, that in all things distinguishes the strong soul from the weak - Thomas Carlyle

There is great pleasure in achieving and succeeding when others say you cannot. The goal is not to never fail, but to be able to pick yourself up after a failure, learn from it...and move on.  With enough patience and perseverance...soon your difficulties and obstacles will disappear.
