I am going to address the idea that everyone else has as well; stick it out. The first year to any job is going to be difficult, regardless of the trade skills you learned. Think of it this way, a hair stylists, a mechanic, a chef all go through the same years of struggle as they gain experience. Time management will come as you establish a routine and the abilities in your newly learned field. Do not let your self doubt and anxiety cripple you-- it will rob you of any job, any education you have or any other ones you think will fix it in the future. Take time, practice, keep asking for advice when you need it. And keep working. So it takes you and extra half an hour? so what? you're doing it well aren't you? Keep at it (and takes breaks so you don't get burnt out).
