Quite oversaturated. And to build a brand centered around improving looks. You need to a mogger who had a crazy ascension. No offense mate, but you’re not there yet. Invest time and money into something that will give you a higher ROI. Start with things you’re good at from an abstract sense, because at 18 you don’t have any specialized skills. Narrow down to a specialized skill, train that skill, get very good, and then market that said skill to a niche market. Alter your strategy with each iteration, and have a revenue stream from something stable (like a job) to support you and use the income to invest in the business.
