This is important. People will always know your true motives whether in the short term or the long term, they will always know your true motives. So, do everything with a kind heart and with love. My New Year's Resolution was to think, do, and act with one thing in mind: "Others Before Self". When you do something with love, you're doing it for the betterment of all.
Please remember this as we go on with our day and week and month. Love yourself, love others. It will always pay off in the end.
