CS CORNER Sunita Rai
Discipline is often painful in the present, but regret is far more painful in the future. The effort we avoid today doesn't disappear.... it returns later as missed opportunities, unfulfilled dreams and the question of 'What if I had tried?' Every small act of discipline is an investment in the life we want to build. Stay consistent, even when motivation fades, because temporary discomfort is a small price to pay compared to a lifetime of regret. Choose discipline today, so you don't have to live with regret tomorrow.
