Practically, what should we be using our CPF for, other than for retirement? Or is this purely saving for when we stop working?

I feel that people need to have a mindset change that CPF is a retirement tool. For me, I think of CPF as a get-rich tool, hence it forms part of my portfolio to get rich and as a baseline for a financial safety net so that it help me to feel more secure and to balance my financial emotions for equity (read: riskier) investments

CPF is a tool for saving and building up our funds when we are young. However, it is a tool for retirement when we are 65 years old.
