Determine your "why"
First of all, sit down with yourself and figure out the reason you want to move out. The common sentiment in Singapore is that renting is a waste of money, but try looking at it from a different perspective – moving out on your own could be an investment for your personal growth.
However, moving out may not be for everyone. There are questions you should ask yourself. Is it financially viable? It would make less sense to move out now if you're saving up to buy a home next year, for example. Another question boils down to filial piety. Are your parents growing old and reliant on you to take care of them?
