The beauty of Islam is that nothing is wasted, nothing is meaningless. Giving some water to a thirsty homeless animal can wipe out all your past sins. Birds and animals eating from plants you grow in your garden is a charity. A compassionate touch on an orphan’s head is appreciated by God. A smile and a good word are praised. Putting a morsel in your wife’s mouth is a righteous deed. Cherishing your own family is a charity. Honouring you parents is highly estimated and rewarded.
Even your pains, physical and emotional, great and small, nothing of them is wasted or meaningless, all are counted and compensated. This is the nature of having a trade with God, The Most Generous.
