The acts most pleasing to Allah are those which are done continuously, even if they are small. and when 'A'isha did any act she did it continuously.
Sahih Muslim Book 6, Hadith 258
← Previous Hadith I asked 'A'isha, the mother of the believers, saying O mother of the believers, how did the Messenger of Allah (ﷺ) act? Did he choose a particular act for a particular day? She said: No. He act was continuous, and who amongst you is capable of doing what the Messenger of Allah (ﷺ) did?

Sahih Muslim Book 6, Hadith 257 Next Hadith → What is this? They said: It is for Zainab. She prays and when she slackens or feels tired she holds it. Upon this he (the Holy Prophet) said: Untie it. Let one pray as long as one feels fresh but when one slackens or becomes tired one must stop it. (And in the hadith transmitted by Zuhair it is:" He should sit down." )
