Apart from picking great advice from here and experienced techs and looking and admiring to their work, which helped me big, big time, there is one other thing that I think helped me, and that is myself, and I'm not being sarcastic, please don't take it this way. Here's the thing:
I decided to work right after nail school. Opened my business and knew, what I earn, that much we will eat. I didn't found this place untill just last year. I certanly wasn't brush - related artistic person, so that I might have had 'my way' with the brush already. But I decided, or just knew... or to be more accurate - I did not doubt myself, just went with it. My nails were not something to be proud of at all. But right after nail school I was producing nails for paying clients. I had a good product, so no matter the shape and the form, but at least nothing lifted. That gathered my first clientele.
All that happened not because I'm some genious fast learner, oh no... the opposite! But you know, it seems like great percentage of our abilities, or let's say - development of our abilities - depends on our faith, selfconfidence, call it whatever. Just don't beat yourself with pressure!
So for starters - just decide you want to do nails. Or better yet - decide that you're god at it! Of course you will look at your nails and compare them to others and see what you need to improve, but just stay on this road, and don't give up and you'll soon be seing results.
As pathetic as it may sound - but for me proven to be true - whatever you put your mind to - you can do it. Whatever that may be. For example, you know what I did? My friend needed a jazz singer for his band and asked me am I intersted. I just said - ok, why not. Haven't been singing for 15 years, and that was in the church. But I picked the most difficult horrid Chick Corea song (I didn't know it was horrid and difficult :green
and just went up there and sang. He dropped his jar on the floor. But once he told me that this is hard to sing, that song is difficult and that pro singers are affraid to sing his music, my voice crashed. See my point?
