Overview
The word ṣadaqah in the Sunnah is broader than the English 'charity'. It covers everything a Muslim can offer — attention, effort, cheerfulness, guidance, silence when speech would harm — done from a giving disposition of heart.

“Your smile in the face of your brother is charity for you; your enjoining good and forbidding wrong is charity; your guiding a man in a land in which he is lost is charity; your helping a man of weak sight is charity; your removing a stone, thorn or bone from the road is charity; your pouring water from your bucket into your brother's bucket is charity.”

What this means
The wide definition matters. It means poverty does not exempt a person from being generous — they can still smile, guide, help carry a load, pour half a bucket. And the secret-charity hadith teaches that at the highest end, giving becomes so purified that even the giver's own memory of it is starved.
Public vs. secret giving
The Qur'an (2:271) says openly giving charity is good, but doing it secretly and giving it to the poor is better. Classical scholars reconcile this with reports of open giving by saying: publicise the category (so others are encouraged) and keep the amount and the recipient private. Public bragging about specific amounts and specific recipients drains reward and wounds the receiver.
Application today
Every morning this week, look for one act of ṣadaqah of the non-money kind — a genuine smile at someone the world ignores, a message of thanks to someone who helped you, removing a hazard, opening a door. Track them for a week and notice the change in you.
