What made you regret?
I am very happy with my TM retirement so far (single pay and has started receiving monthly payout after waited for 5 years accumulation period).
I used part of the proceed to buy two small Aviva 'retirement plans' (coz the proceeds > my expenses every month) under my kids' names with policies assigned to me - pay $3663/year for 15 years, accumulation period 10 years, then payout period 30 years. The guaranteed part is about 2.6% which I find decent enough.

*these if I get to live to see them paying out then I will continue to collect the money, if not, will form part of my assets to be given to my kids for their retirement.
Basically for this kind of 'long life' products, need to be patient as time flies and the waiting period will be 'soon' over and the seeds begin to bear fruits.
