Lots of good unsolicited advice here from Kevin Kelly, the executive editor of Wired in its heyday and a bunch of other good things. Like these:
Buying tools: Start by buying the absolute cheapest tools you can find. Upgrade the ones you use a lot. If you wind up using some tool for a job, buy the very best you can afford.
Pros are just amateurs who know how to gracefully recover from their mistakes.
Separate the processes of creation from improving. You can’t write and edit, or sculpt and polish, or make and analyze at the same time. If you do, the editor stops the creator. While you invent, don’t select. While you sketch, don’t inspect. While you write the first draft, don’t reflect. At the start, the creator mind must be unleashed from judgement.
To make mistakes is human. To own your mistakes is divine. Nothing elevates a person higher than quickly admitting and taking personal responsibility for the mistakes you make and then fixing them fairly. If you mess up, fess up. It’s astounding how powerful this ownership is.
