97% of Buffett’s wealth was acquired after the age of 60, and 99% of it was earned after 50. We in our 30s are truly still so young. If we want to achieve true freedom one day, we must never stop learning and refining ourselves. It’s okay to go slow, but we can’t do nothing.

Actually, if asked, it is better to achieve financial freedom at a young age than at an old age. Because to be successful at an old age, of course there are many things that must be avoided, especially in terms of disease.

Yes, health is certainly the most important investment than anything else. At the very least, we should have a strong and healthy bodyI admit that at the age of 20-30 years, that's where your future path is determined, lulled by just playing around or starting to think about your future fate by starting anything, working, investing, being self-employed or being creative. But what is certain is that at a young age we must apply a healthy lifestyle and consistent regular exercise. In addition, start saving every month, don't buy unnecessary things, work hard but effectively, always see opportunities and chances, learn a lot from experienced and successful people like Buffett.
