My favorite saint is Therese of Lisieux.
One of my favorite quotes from her is:
"Love proves itself by deeds, so how am I to show my love? Great deeds are forbidden me. The only way I can prove my love is by scattering flowers and these flowers are every little sacrifice, every glance and word, and the doing of the least actions for love."
Basically...little acts of kindness are just as 'great'. It's the little things in life that count.
