| In my experience:
|
| 1. Start building stuff that is hard to build that requires

| know how to build
|
| 2. As you encounter problems, you'll have to scour for
| solutions (AI doesn't know these things due to lack of
| training data). In the process you will find people who are
| also working on these problems. Ask these people well-
| formed, intelligent questions.

| Then again, -j1 is nice, when you need to time a break.

|
| The two articles I saw about this both emphasized that the high

| CPU that implied it would be lower performance than the 9800X3D.
|
| Most of the sites I check regularly have been pretty good about
