Learning something new generates new neural connections, and optimizes existing ones. It helps prevent cognitive decline that is normal during the life cycle. You can practice a new physical activity, read something different from your regular interests, or visit a new place amongst various other things.
Set a weekly goal to learn something new. You can schedule a specific time to do it. Ideally, it should involve something different from your common routine, your usual places and people.
To get more benefits, try to match the new activity or knowledge with your goals. For example, if you are an entrepreneur, try to learn something new about your industry or a related field.
Choose the time that best suits your routine.
