Me...
First I'd set up trust funds for each of my children, not too much because I do think wealth isn't really appreciated if you haven't had to work for it a bit. But enough to give them a good deposit on a home & a bit of money to spend/invest as they chose.
My Mum, A nice little holiday & again, some long term secure investments with some healthy returns. I don't ever want my Mum to end up trapped in the poverty of a pension, it might not leave her wealthy, but at least, even if something happened to me, she would not end up shivering & cold & worrying how to pay the power bill.
For myself... a set amount to travel & play with, & the rest invested, some in long term secure investments with compounding interest. Let that sit & grow for now. My retirement fund.
The rest, mostly in property. Let it sit while the tenants pay it off, using the equity in the houses to slowly expand my portfolio... some for eventual rental income as the morgatges reduce enough, others to resell when their capital value peaks enough to make it worth it.
And a little bit... money I can afford to lose... for stocks & shares.
My primary goal... A high enough rate of return that I can live comfortably off the interest for the rest of my life. Myself, I don't even believe that the 'pension' will even exist by the time I retire & I'm 38yo. The govt has already pruned it to the barest survival minimum & is pushing govt backed retirement funds with such vigour that my feeling is that their goal is to eliminate it altogether.
As for charities? Well if I can bring in enough I can support any charity I choose to as I go. But even if I can't afford to, at least I won't end up being anyone elses charity. Been there & I don't like it.
Can you tell I've thought about this subject? Although I'm not waiting for some windfall on high.
When I was 25 I didn't even know that I needed to be saving for my retirement, now I'm 38 & I've already left it, if not too late, then definitely to the last minute. Gotta lot of catching up to do.
