So what can I do?
Just imagine what you can do better. Dance, songs, pictures, microcontrolling, cooking, cosmetics, bike stunts, or daily movies, news, sports updates. You must be interested in something in these things. You can choose and make video on it.
Can you ask, what is the profit?
Brother! That came one thing back and forth. If you are interested in setting up your channel, then definitely the video creation will be good. No need to upload videos every day. Upload one or two months of good video a week. Do SEO There will be no shortage of subscribers after six months.
