the only thing I can suggest is do something you are passionate about. something that wont burn you out and something you just enjoy doing.
its different for everyone but can be reaction videos, gaming, cars, whatever! coming up with something unique is hard now and days.
like for me, its offroading, dirtbiking. i mean its fun filming, so it goes hand in hand. But I do like videography so I am slowly mixing those in as I get more footage and get better at ideas.
ideas do come though almost like a skill as what you should do next lol
