Don't be afraid to use an "oldie but goodie" when you've reached a roadblock on the path to solving a problem—it might just be your best solution.
There are hundreds of options for brainstorming--and new ones arriving all the time in our fast-paced digital world. However, for some a classic approach might be better than the latest app. It's all about finding what works best for you, taking into account learning styles, preferences, and any props you might have available. The next time you're stumped about a decision or can't move forward, try out one of these traditional approaches. You might be surprised by how effective they (still) are.
