How can I become a rapper?

Write a lot. Learn new words. Read Everything. Use imagery. Immerse yourself in diverse forms hip-hop. Record. Practice. Find places to share your craft. Learn marketing and promotion strategies. Use social media to advertise you as an artist. Have a clear message. Work hard. I rapped and did shows for almost 7 years. I have picked up a variety of skills such as public speaking, stage presents, and creative writing that I have used in multiple jobs.

Being a rapper is a great dream but it would probably be wise to have a plan b just in case your rap career doesn't take off like you want. Don't be limited to one thing.
