What this means in practice
Ninety days is the planning horizon the site uses because it is short enough to act on and long enough to produce evidence. A quarter supports a course, a proof project, and a real internal or external career conversation — the three moves that actually change trajectories.
Each occupation page frames its transition pathways this way: immediate skill actions, a visible work sample, and a decision point. A Tax Preparer, for instance, can spend one quarter learning exception-resolution workflows and building a controls checklist sample rather than vaguely planning to pivot someday.
