I am a 25 y/o who recently started working. It's been 4 months and I have already saved $10k. Any long term investment advice?

Diversify globally. Invest regularly. Stay invested.

Above that, there isn't much more that's needed.

The nuances would be how exactly to craft this portfolio and the risk strategies you take now and when you're closer to your desired financial goal.

You're young and can take risk now, but will not be able to take the same kind of risk when you're 60.

So having a 4 decade view of your investmenr portfolio and the shifts you'll make along the way will give you some perspective of what to expect and what to expose your portfolio to.

I would suggest you start an RSP on any good diversified equity unit trust or one of the robo advisors who offer a diversified portfolio of etf’s from across the globe..

start small and set aside an amount you’re comfortable - say $500 or so.
