I’m a 33 year old long term investor, setting and forgetting for 30 years. I’m 100% VTI, how dumb or smart am I?

Pretty much the title

I’ve had a Roth IRA and a taxable account for a few years. Both are 100% VTI.

There’s no perfect plan or else everyone would do it. I don’t have anything international obviously, if that was the way to go then wouldn’t everyone do VT?

Is what I’m doing a good plan? I don’t see why any young person would need bonds any time soon

My simple goal was/is to just have something low cost that tracks the S&P 500, for the long run.

I’m investing about $11k total annually

Let me know what you think! Thanks!
