Saying that you are working on your personal development enough is not enough because until you don’t really be successful in whatever goals you set for yourself, then it means that you need to work even harder than before.
In life, you will meet with ups and downs, successes and failures, negative and good people but overall what matters really is how you accept and react to things. It’s all about you. It’s not about others because they have their own life to live. It’s about your life and your personal development. That’s why it’s very important for you to work hard enough on your personal development.
