Research how other people have approached the issues you are trying to solve.

Expose yourself to new ways of thinking by learning something new.

If you feel overwhelmed by how little you have progressed, switch to working on mindless tasks that require little attention and allow the mind to wander. Wash the dishes, organize your bookshelf, or do laundry. 

By returning back to a time and place where you felt less discouraged or unproductive, you can harness the positive energy you had back then to push yourself forward and accomplish even more.

Spend time researching what your acquaintances, family members, and friends have been up to on social media. It will keep you connected and possibly give you ideas on how to approach issues.

When you are feeling stuck, start writing about whatever is on your mind.
