How Should an 18 y/o Start his Entrepreneurial Life Stepping into Uni?

Hey everyone, I am stepping into first year comp. eng, However my all time dream is to be an entrepreneur and launch my own business, I’ve been trying small ways to make money online such as web development, being a closer for certain businesses (basically ended up almost getting job scammed).

I have the discipline to work as I have excelled in many areas of my life such as school, work and fitness, I have a burning desire to hustle but I don’t know what to work on, theres so much people saying so much different things online and I don’t know what to follow.

And I see so much of these kids from around the world creating solutions to real world problems, but I feel like I don’t have that level of creativity.

If any of you were in the same situation as me and found your way up, I would really appreciate your advice on what to focus on!
