This mission is different from others, with less structure in it, as it is an exploration of self. But still, there are a few things that can help you.
Look at it in a zoomed-out and zoomed-in perspective.
1. Zoomed-out:
If you have defined some life goals in the Star of Spirit, pick one up and immerse yourself.
As you face new challenges, you will come across new facets of your psyche. Once found, polish them.
For example, while learning martial arts, if someone cheating in a fight makes you lose your temper, you reconcile with anger by turning your reaction into a response. You realize that it is not that anger is wrong, it is how you put it out that is wrong.
Repeat this process with different goals in life which scare you but keep you motivated as well. This is a life-long process.
2. Zoomed-in:
Seek novel experiences in day-to-day life with an open mind.
Jump into tasks that you usually avoid or never thought of. It could be a debate, writing poems, dancing, and so on.
Each experience will help you expand your knowledge of yourself and get you closer to self.
The bonus is that skills from one field often help in another, so nothing goes to waste.
In the end, there is no “right” path. All that matters is the right attitude, which can be inculcated simply by following the zoomed-in and zoomed-out perspectives above. Thus, your view of looking at challenges changes, and you embrace them as a way of self-discovery.
P.S.: Remember, individuation needs active participation. Do not fall into the rut of reading piles of books or meditating endlessly (still, some reading and reflection are always good to unpack the mind).
P.P.S.: Also, you will realize that fulfillment is less about achieving the goal, and more about setting on the journey. Just make sure that the path comes from you, and not from someone else. Your interest makes it easier to face the challenges that hold the key to yourself.
