In this world there will always be someone to disagree, pass judgement, shake their head, or voice an unwanted opinion after we do or do not do something they think we should. How often do we second guess ourselves after deciding to move ahead with something we feel is right? Do we let the doubts and negativity of others tap away at our peace and confidence once we've moved forward?
If our heart is in the right place and our actions reflect that, that is what matters most, period.
"Many of the deepest regrets of tomorrow can be resolved by following the Savior, today."
-Dieter F. Uchtdorf
