While the market was a very good bet for the last 50yrs, its not a guarantee.
Especially in the current climate you should be fully aware that it's significantly more risky to start investing today vs 10 yrs ago.
(Riskier doesn't mean it's necessarily a bad idea. It should just be a conscious decision under the acknowledgement that the upward trajectory is not certain. Especially in current political climate - and that "hodl"-ing doesn't necessarily mean you'll eventually get back what you invested, if a downturn manifests)
