If you're intent on CTB, the first step is to choose a method that works for you, one to which you have access and the materials. Then learn all you can about it - what preparations are necessary, what to do, what not to do, the pros, the cons, anything and everything. Then get everything together you need and formulate a plan as to when, where, and how. Ask lots of questions about your plan in the forum. There are no dumb questions. Preparation is the key to success. Good luck.
