90 deg corners... Get a square that you trust. Learn the 3-4-5 method.

patience.

Wear hearing protection.

You more than likely will probably never need a table saw, jointer or a festool domino tool.

Tools I'd get first:

- japanese pull saws

- good chisel set

- a track saw... and a 2.4x1m.2m sheet of foam to cut on

- a palm router, learn how to make all your own jigs

- 12 irwin quick clamps. if you also prefer and can afford, 12 t-track f clamps.

- an impact dril, and a normal drill

- a decking drillbit

- a marking guage

- pencils

- a speed square

then

- make or get saw horses. and 2.4mx1.2m sheet of formply

100% avoid:

- 90 corner clamps.

  instead get larger 1.2m irwin quick clamps or 3d print some corner protectors for a strap (assuming you're doing boxes)
