Of comparison. Comparing your accomplishments, comparing your failures, comparing your strengths, comparing your weaknesses. When you spend so much time comparing yourself and in competition with others you actually can’t see yourself very clearly. I remember when I was younger, my family always had fun doing riddles and maths problems together. I solved the riddles yet maths always slowed me down and instead of seeing how I solved the riddle, my mind was constantly berating me for not being good enough to solve the maths problems. I compared myself to people who were years ahead of me in life. I became so caught up in this weakness it drove me to dedicate the rest of my academic years to becoming the best I could be at maths. I did and what I realized was I actually enjoyed maths when I was not comparing and competing with others. When you actually just concentrate on doing the work to become the best version of you, life’s a lot better!
