It's that time of year again: another year down, and a new year is just around the corner. If this past year didn't treat you as well as you had anticipated, then don't beat yourself up over it, because it happens to the best of us.

Take the lessons learned (or, the blessings in disguise) from the year prior and use them to make 2016 your best year yet with these 10 inspiring quotes for the new year ahead.
