Well, you appear to have learned one lesson: make sure that you have one fully functional modern computer available for use, just in case you break another.
Other rules:
1. Don't go beyond your skill set. Watching another person perform an exercise is one thing but it is more challenging to attempt it on your own. Don't attempt anything unless there is a high probability of success (or you don't care).
2. Don't be afraid about asking sensible questions. But please do a little bit of research in advance.
3. Go to the stationers and buy a notebook. Write your contact details at the front of the book, because you will mislay it. Record your experiments in it. Teach yourself to draw.
Edit: contact details in notebook.
