Translation of "accomplice" into Swahili

To get the most done, I have tried to be motivated by the principle, ‘Indecision is the thief of time; procrastination is its chief accomplice.’”

Ili nitimize mengi iwezekanavyo nimejitahidi kufuata kanuni hii: ‘Kusitasita ni mwizi wa wakati; na kuahirisha mambo ni msaidizi wake.’”
