People may not tell you how they feel about you

Don’t make people a priority. You’ll be disappointed. Yes, do your best & cultivate good relationships but don’t hinge your hopes on them. They’re human & they have weaknesses. Put the Almighty at the top of the list always. He will give you insight & wisdom in your journey!

Be genuine when correcting people’s mistakes.  Do it discreetly, in the most subtle way. It shouldn’t make them feel embarrassed or unintelligent. Soften their hearts with kind words so they feel your sincerity. Be empathetic always. Good actions give strength to ourselves and inspire good actions in others. Great thoughts speak only to the thoughtful mind, but great actions speak to all mankind.

People may not tell you how they feel about you, but they will always show you. Pay attention.

Indeed! One's approach is enough to determine whether person is truly trying to help others in correcting their mistakes or just trying to belittle to show that he/she is more sincere, mature & perfect than others. 

Every effort has its own return back in our life as it depends upon our real intension behind certain actions. So, be sincere with one's approach in every action because what goes around comes around.
