No three words I could think of resonated with me so off to google I went and found:
I Become Myself
This instantly rang true to me as I have been feeling like I am really becoming myself lately, knowing more who I am and what I like and kind of "settling" into myself like into a comfy armchair.
Of course becoming oneself is not an overnight thing, there are many steps to get there and I don't know if one ever gets there until the very end or whether there are different stages of becoming oneself.
I did a play on words and tried to make as many different three word phrases out of the original one as a path to becoming oneself.
I used Neocolour II and Inktense pencils.
