I thought that it is possible to be an expert in my 30 at the age of 30, but I'm not an expert yet. In my journey at work, I sometimes felt week, It doesn't mean that I'm not a methodical person. My job is quite free and gives me an extraordinarily fruitful feeling but it also requires me to be the person who is perfect in organizing some datas. That is why every year I buy a notebook for so I can manage my schedule well. My goal at the age of 30 is to finish writing personal organizer but it's not easy for me to do it every day.
