After sweeping for 3 months ...... then u adjust those skills base on your capabilities .
Everyday u will improve .
Today Raffles City got one to Yishun , then tmr i will never go Raffles City again , i will try Bugis Junction .
If at Bugis Junction took one to Airport , and u love going AP , then plan yourself to go Bugis Junction everyday ... until u get one to Woodlands .
Consolidate your routine .
