Personal finances
Try to avoid panicking at the state of the market right now. Chances are, your financial advisor is swamped and handling the same nervous phone calls from various (or almost all) clients. Draft up any questions you might have and consider emailing them instead.
Future planning
Talk with your family and/or draft your own personal notes around the next 5 years, 10 years, and so on. Consider key goals, possible challenges, "what if" scenarios, and identify areas that can be addressed in the short-term.
Revisit your insurance policies
Haven't talked with your insurance provider in a while? Now is a great time to consider your current policies, look at any gaps - and you may find an opportunity to save money in the short-term. While many people are driving less and staying home, you could qualify for a discounted auto policy for driving less miles or having only a part-time need for your vehicle. Talk with an agent and find out what your options and opportunities are.
