Here's one of my favorite personal frameworks on what to focus on in life: Life's Ring of Importance.

You're at the center because you are the most important in this world. Nothing else matters if you cannot take care of yourself and make yourself stronger.

At the center, you are comprised both of your mental and physical robustness. The most fundamental question to ask yourself is: Is your mind tough enough to surpass mental challenges and your body strong enough to conquer physical ones?

This is the most basic foundation for you to build personal wealth, happiness, fulfilment, etc..

Once you are certain that you have built a strong mind and body, that's when you move to the outer rings.

Save yourself before saving the world.
