When I realized I was grown up, I had to forfeit my obsession with Lego. I used to build and play with it every day and I really enjoyed it. But when my cousin told me I should stop playing with Lego because it was childish, I listened to him and I forced myself to stop. I had to realize that there were more serious things in life that I should pursuit like studying or other hobbies which are less childish.
So basically I think I just recognized the need to focus on other priorities. On the other hand, I think it is also important to hold onto the things that bring us joy. Anyway, my love for Lego as a child was beneficial to me because I managed to incorporate it into my logical reasoning skills. I often try to see the pieces of the problem – how they fit together, and what solution could work.
I think it is amazing how childhood interests can shape our abilities and skills later in life. So what I do now is to continue to develop and apply my logical reasoning skills in my current endeavors – even though I have never been good at Maths, which is a shame.
