Chanced upon this forum recently and admire that so many here have successfully build up their saving and retirement. I hope to get some advise.

My wife and myself are in early 40's with 2 young kids (3 and 5yo). Our combine income/saving are

Income = 170k pa (exclude bonus)
Savings= 30k
Stock=150k
CPF OA = 170k
Property (hdb) = 600k (fully paid)
Passive Income= 5k pa (Stock)
1 car (6 year old, fully paid)
Debt = 0

We hope to achieve
- more passive income
- invest in property (but have little saving)
- build up education fund for children
- build up retirement fund

Thanks in advance.
