Most importantly, the amount of things in your shed increases exponentially with respect to time.
In the blink of an eye, you'll have old lawnmower blades (for when I start forging), a full shelf of two stroke engines (shame to throw them away, when they almost run), at least 3 power tools that have been used a total of once (but they were on sale), a "random fasteners" drawer, and an entire woodworking area. *
* Woodworking area may only exist in your mind if you're younger than 50.
I believe that comment was to be written as "If you are younger than 50, woodworking area could be still in plans. If you are older, you definitaly already have woodworking area".
My tip for anyone in that position is to start buying stuff, I bought the biggest portable table saw (in retrospect, not the best approach) I could find and progressed from there. At the time I lived in a flat and worked on a balcony.
My first woodworking project was to make a wooden work bench on which I could do subsequent woodworking. The bench is still firm, solid and in use 15 years later.
