Welding

I start my welding apprenticeship tomorrow. Ever since I thought of the idea it's occurred to me that I could solve a lot of problems for cheap if only I had the ability to weld. My fear now is that once I get good at this I'm going to try to solve all my problems through welding regardless of its practicality. Also, I would just like to reiterate to my mother that, no, I will not blow myself up doing this.
