You are never too young to plan for retirement, sooner is better than later. No one is gonna take care of you except for yourself.
For me I never plan to retire, I just want to achieve financial freedom before 35, but i'll still keep working/consulting/freelancing/volunteering as I like to do that.
I don't want to end up being senile at a young age :p
That is the message. Don't want to end up being senile!
