I got a job in a nail bar when I first qualified, and it took around 6 months for me to have a good amount of regular clients that would return without fail every 2 weeks.
5 years on I've just opened my own salon and I have a healthy amount of regulars. I'm not rich, but I pay the bills lol.
Keep doing what you love and put the work in to be the best you can- lots of practise, increase your knowledge base all the time and always seek advice and further your training where you can.
When you can convince your ladies and gents that they can't live without you, they'll keep coming back x
