I cannot grok this statement. The older I am the bigger risks I was able to take because I had accumulated more financial independence. Why would you be able to take more risks when you are young?
When I was 23 I had little savings, little assets, lots of debt I was worried about paying off, and felt like I needed to work or I was going to be homeless and starve. I took the highest paying job I could find, and worked until I had enough experience and network to find a higher paying job. I took no risks.
When I was 33 I took large career risks because I had no debt (outside of low mortgage payment), lots of savings, plenty of assets, and a professional network to fall back on if my risk didn't pay off.
