If I’d start over I’d give myself these 3 tips:

Use the map actively to note down everything, big trees, different stones, warm/cold/rain areas, prospecting later on too, is very helpful. A fully fledged out map saves a lot of time later.

First order of business as in any survival game is food then shelter. Berry bushes can also be picked up.

If you find copper bits on the surface, dig down :)
