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. 
At the very least, we should have a strong and healthy body
Saying that a 30yrs old is still very young and it's okay to go slow depends on our passion. For me making wealth at an older age is not very appealing to me, it's amazing that buffett could achieve so much success later in life but we all have our separate priorities. Personally I think having wealth and financial freedom at a younger age would be incredible, with wealth at a younger age just imagine traveling, pursuing your passion, exploring the world and enjoying life with your loved ones. I wouldn't want to be like buffett because what's the point of being successful when I've missed my youthful age, time and energy to enjoy my wealth. At the very least, we should have a strong and healthy body
