Welcome Filip :) I am also just a few months away from defending my masterthesis - medicine it is (was) for me ;)
Glad you found steemit, gave you a little boost + a resteem (=a share of this post) via Hive account@welcoming - You can find other new users there!
Oh and by the way, always try to use all five tags for more visibility!
To this one i would probably add "science", "introducemyself", "poland" + one other f.e. ;) greets!
