It's hard to give specific advice, but I think reading and posting on this forum will help a lot.
There's the general rules of thumb around the 4% rule as well.
For my own part, in addition to looking at how to find out a good investment strategy (i.e. asset allocation) I'd also look at the things that are within your control: taxes and fees.
Taxes can be hard to control, but there's a number of things you can do to maximize income.
Fees are very easy to control once you know what they are.
The way I think about this is if you nave $730,000 in investable assets... that should provide you with roughly $29,000 of annual income (using the 4% rule).
So if you consider that your income stream, how much of that are you spending on various things before you can spend it on your life. That's where taxes and fees come in.
Fees are easy... if you are paying on total assets (say 1%) then you are paying $7,300 per year in fees. Divide 7300 by 29000 and you get 25%.
If you have that money in ETFs or mutual funds with an average fee of 0.15%, you will pay 1095 or or 3.7% of your income. So you can raise your income by quite a bit if you happen to pay high fees and you move to lower fees... and that's without taking any market risk (actually you'd most likely be lowering your market risk as well
There could be similar benefits via tax optimizations, but that's case by case and if you look at some threads here as well as asking questions, people on the boards are very knowledgable and someone has seen almost any situation!
All the best!
