I think both social and technical skills.

In the social side, I aimed to be more social. Being able to go to a new group, make some friends there but still being myself. Being able to chat with some random girl at the train was unthinkable for me years ago for example. It is a fun adventure to try to improve in that regards, idk I take it as a little personal challenge.

I'm trying to be more disciplined, sticking to a routine, doing new sports, put some effort into those and see the progres, etc...

On the technical side, I knew I wanted to get into 3D printing since a long time ago and finally got into that, learning about it, improving. New objectives regarding work for the mid/long term.

I still feel like there is something more meaningful that I can do but it takes time for me to articulate what it is, all of the above helped me to understand a bit more what that meaningful can be.
