Dictionary.com gives me this definition of Diligence:
constant and earnest effort to accomplish what is undertaken; persistent exertion of body or mind.
And I think something is to be gained from the definition of Diligent, as well:
constant in effort to accomplish something; attentive and persistent in doing anything; done or pursued with persevering attention; painstaking.
Welcome, 2013. I look forward to a year ahead of growth, as I learn to be diligent in my life.
