The accounting world is changing fast. Computers and AI now handle much of the boring, repetitive work that humans used to do by hand. This is great for saving time and catching mistakes, but it also introduces a new challenge: "mental rust" or “cognitive atrophy.” If we rely on computers for most of our thinking, our own problem‑solving skills can weaken. Recent studies suggest that heavy reliance on AI tools is associated with lower scores on some critical thinking tests. When we stop practicing how to solve problems ourselves, we may be less prepared when something unusual happens that the computer cannot handle. To stay sharp, accountants need to find practical ways to keep their brains working hard. Here are 100 simple ways to keep your mind strong in the age of AI.

When Your Client’s World Is Bigger Than the U.S.
A lot of client meetings still start with the same assumptions: W-2 in a U.S. state, mortgage nearby, a 401(k), maybe some RSUs, and a college-savings plan. Yet many of those “simple” clients now own an apartment in another country, freelance for a foreign company, or have parents wiring money from overseas. The tax code does not see those details as background color; it treats them as organizing facts. This is where citizenship, residency, and domicile quietly step onto center stage. For planners, the challenge is not memorizing every cross-border rule. It is knowing when a client is no longer “just domestic” and shifting your planning framework before you stumble into penalties, double taxation, or blown opportunities.
