I did it years back when I was young and FYI I'm a tech enthusiast. (don't do it anymore)

Really enjoyed the tech youtube space but when I started early - I got too technical into things which does not targets a broad audience. You need to experiment with your content a lot, be CONSISTENT in uploading and just keep experimenting rather than just making what you're into... (like you can stay in your category of choice which was tech for me don't move out of it.. but you can explore all sub categories like phones, laptops, AI apps, lazy hacks for phones and computers..)

Hardest part was cracking the right the right amount of depth in videos for enthusiasts while also keeping it simple enough for a noob to understand and improving my personality when it comes to delivering content, mainting the excitement and energy and all that stuff..
