I believe I first realized my love for this whenI woke up to go to work the day after I lost myself in Blender and was modelling and playing with random simulations until 4AM.
I realised it already in my teenage years. Since a child I loved to draw and play videogames and over the years that interest only grew adding cosplay to the list where I mixed the two interests.
Around that same time I decided that working for a game company was what I really wanted.
