...pay more attention to my Super.
I would take mental ownership of it rather than thinking it’s just something for old people to worry about.
First up I’d consolidate all of my super into one account to avoid paying multiple sets of fees. I’d also check to see if I was paying for insurance that I may not need at the moment, and if it offered the best deal on income protection insurance. I’d seek professional guidance to review the investment mix and whether it was appropriate for my long-term savings goals.
And despite all the other things I want to do with my life before retiring, over the years I’d keep a close eye on my contributions to ensure my employer is paying what they should, and watch the balance grow to a big enough nest egg to give me financial independence by the time I eventually retire – if I ever want to.
