YAY!!!!!! One more vegan in the world!!!
Any tips? Just one: print out dozens of vegan recipes from the internet. The simple ones, that do not require processed vegan stuff (like "fake" meats or "fake" cheese or "fake" egg replacers). You don't need all that stuff. Simple, natural vegan food is great.
And don't worry about your leather shoes right now. In time, you will be able to replace them.
And if ever you realise you've been using a household product or something that has an animal product in it, or has been tested on animals, don't freak out. There are SO many hidden ingredients, SO many things tested on animals, that's it's easy to make mistakes in the beginning.
