Listen. Don't think about how long it will take to reach this or that. It will only discourage you. Come in everyday , do your job safely and at a fair pace and focus on what job you can do when you aren't here that you actually enjoy and pursue that and strive to be great at that job. Use this job as extra spending money and free insurance and don't sweat the years. Time will fly by. Trust me on this.
You can make more than that with no high school diploma cold calling people In an air conditioned environment with lunch breaks and attractive females to look at. At least 20 years ago you could. It might be way more now...
