Speaking to solely to my younger self, mind you, no one else, and taking into account mistakes I had to learn from along the way from there to here...
- try everything, absolutely everything, and give it at least three honest chances before deciding whether to never attempt it again, for there have been several loves in your life that were not immediate passions;
- put your money into quality supplies and equipment, for they are an investment in your future comfort and joy;
- maintain your machine as well (or better) than you do your vehicle, for you will often drive it at night and on weekends when no mechanic is available;
- never buy precuts or kits, for you learned how to cut fabric before you started kindergarten and there is no need to pay someone to do it for you now that you are grown;
- never, ever, hold back on putting yourself into your work, for it will speak with your voice long after you are gone.
