By serving others we serve the god inside of them, making god happy with us which can make you happy and do want you want to do. We can technically serve others by donating to thadiyaaraadhana(Serving free food to others) right here. Serving others can also increase your bhakthi towards the Lord by servng the god inside of them. With all these positive outcomes, why not donate at least 10 dollars if less than 1 dollar can give a free meal. Once you donate god should be pleased with you if you really donated to your level best and your wishes may be fulfilled. “Serve All Beings As Service To God”.

If you do not donate or serve others food, then you could just serve others at your local food shelters or start doing that. Increasing the sa:tvic qualities in us and leading us to a higher path in life.
