It's all about value creation, and getting maximum profit out of this value. I forgot to mention that you should read on management. How to manage people, motivate them and help them move to your desired goal. Body language and communication skills are things that people often forget to become better at, but you should focus on this. Getting skillful/proficient in what you want to do, should be your primary goal.
Create good habits. Throw away the unproductive and bad ones. Time consuming activities that don't revolve around learning or anything beneficial to you should be dropped and replaced with something better.
Fear is fake, it stand for false evidence appearing real, basically it is a useless impulse in this day and age. It might have been in good use when we were caveman and we had to fight other primitive animals for food. But today we human beings live in a relatively safe environment. So you should learn to become fearless, and whenever your brain gives you this impulsive response, know that whatever you are fearing never usually happens.
You should learn to not take things personally and focus on reading yourself objectively, a hard truth is a pill you must force yourself to swallow if you want to grow as a person and become successful.
And lastly, don't be afraid to fail. Failure must happen, and you should accept it with open arms. Failure gives us many good lifelong lessons, while success is a lousy teacher. When you recognise one failure, learn from it and never repeat it again.
