I want to retire at 55.
My home is paid up.
I have $500k cash savings.
This cash to spend between 55 and 65.
I will spend $1.5k pm for food, insurance and utilities. $180k over 10 years.
At 65, I will get my CPF Life, $2k pm for the rest of my life.
I lead a simple life.
No car, eat cheap and healthy.

I have many things I want to do during retirement.
No need to spend much money.
I like to read. Can go library. Free.
I like to jog. Free.
I like to go to the park and exercise. Free.
I like to watch movies. Not free but can afford.

Can I retire at 55?
Any advice?
Thank you.
