First, you should select a niche for yourself. What you want to write about, how you want your content to look like, what you are good at. You can make your content specific to food, fashion, fitness, travel or include all of them together and be a lifestyle blogger. Also, influencer marketing is not limited to bloggers, you can be an artist, singer, comedian or an entrepreneur and if you have a good influence brands will be eager to collaborate with you. I am an entrepreneur, my content is basic and simple and I don't even upload much still I reached out to 3 brands and all agreed to do a collaboration with me which made me around $1000 and it took around 1 hour of my time to get some professional pictures clicked.
