All of these are true to a certain degree. I have a few observations. Good tools are an absolute must. I've been at this for six months, and the difference between a good tool and an entry level is astounding. This is true whether its a stitch groover or a beveling stamp. Buy the best tools you can afford. This has always served me well. If you decide leather isn't for you, you'll always get more money back from high quality tools. Good tools inspire me to do better work as they eliminate excuses. Second, is don't let anyone tell you can't do that yet. Or that you don't have the skill to tackle a particular project. You will find your own limits, and they might be much higher than someone else's. Work at your own pace and learn all you can from your mistakes.
