When talking about his own financial mentor, Warren Buffett, Gates mentioned that a key piece of advice he’s been given is to keep things simple. There’s no need to unnecessarily complicate your finances or budgets. Having a simple, yet sturdy plan is not only easier to follow, but it will save you the headache of trying to micromanage or multitask too many different options. For instance, instead of trying to create a complicate budgeting and savings system, consider having a small percentage of your weekly pay automatically sent to a different bank account. That way you’re saving money without actually putting in too much effort.
