What Will I Do in Life?

What a person will do is not foreseeable with an acceptable degree of accuracy because people have free will and their actions are not predetermined or inevitable.

But numerology can reveal likelihoods and tendencies.

Your destiny number is the number 3, which resonates with creativity (among other things). It means you tend to be creative in your expression and tend to approach life creatively. To extrapolate into the future, whatever you decide to do is likely to be related to creativity in some way.

Your life path number is the number 8, which resonates with organization (among other things). It means recurring or persistent events and circumstances of your life tend to be about organizing or operating an organization. To extrapolate into the future, it's likely that you will be involved in organizing or running a business or related activities.

Those are the two major numbers. See the core numbers article about other important numbers that provide nudges.
