You’re already starting to create your personal brand from the day that you actually graduate from university.
Don’t leave it until you’re 45 and then decide, oh yes, I think I might dedicate the next 10 years of my life to doing X. Be very clear on what that lane actually looks like.
You might change that lane at some point in your career, but the knowledge and the wisdom that you accumulate in that lane, you can take into the other lane. But make it very clear within yourself that you have an end-game of what it is that you want to be, and reverse-engineer that.
That might take five, 10, 15, 20, 30 years, but stay on the trajectory, because you will always, always, be known as the go-to person for that one thing that you know for sure in your industry.
