I recommend you go out into the world and spend a bit more time experiencing rather than working. For you, I say you go out and meet many different types of people from many walks of life. To someone else, I might suggest they get experience painting or doing more photography because those experiences will impact their work. However, with your disposition that I’ve observed, all of what you do ties back to people. Developing an ability to write is developing an ability to pass information and influence along to other people. Becoming a better salesperson is learning how to provide value to others best. Improving your ability to speak is practicing the skill of verbal communication—so you can have more of a meaningful impact on people. Your experiences need to be centered around people. This will be the field in which you develop mastery.
