Be sincere and kind in everything you do, and purify your intentions.
If you want to help someone, don’t expect anything in return. If you’re expecting something in return, you’re engaging in business, not kindness.
Similarly, if you are doing some work, give it your best effort and forget about the outcome.
Just remember to give your 100% to everything and everyone for the sake of Allah (God), and He will bring you success and blessings.
