Hardwoods, botanically known as angiosperms, are deciduous and shed their leaves annually with temperature changes. Softwoods come from trees botanically known as gymnosperms, which are coniferous, cone-bearing, and stay green year round. Although a general pattern, softwoods are not necessarily always “softer” than hardwoods, and vice versa.
I regularly use four handsaws in my shop, not because I’m a hand-tool nut but because a handsaw is often the smartest, most efficient choice for the job at hand. Take the job of crosscutting or mitering delicate moldings and miter keys. you could do those tasks at the tablesaw or miter saw, but you’d need to devise a jig to hold the workpiece during the cut, and there’s no guarantee that the spinning blade won’t chew up the workpiece. It’s much quicker, safer, and cleaner to make the cut with a backsaw.
Ultimately, to be a woodworker, just start doing it. Read about it, watch it on television, accumulate tools, look for openings of any kind in a shop, a sawmill, a lumberyard, any place related to the woodworking business. Start making things. Learn carpentry. A good cabinetmaker should also be an excellent carpenter. Build up a portfolio of work, and acquire skills and knowledge any way you can.
