During these worse times, like the world-spread novel pandemic COVID-19 (Coronavirus), the government implemented so-called social distancing, work-from-home, self-quarantine, shelter-in-place, and lockdown. Any activity to avoid the rapid spreading of the virus. Many photographers, artists, and designers' job offers and projects were canceled or deferred. Some may not be working, maybe furlough, or got laid off during this crisis. It can be a very hard time for everyone. It may be emotional or mentally stressful for us being caged not just for a few days but weeks and, hopefully, not for months.
A real photographer can always use any camera. It does not matter if it is a full frame, mirrorless, analog (film), Polaroid, toy camera or even your smartphone. As long as it does the job (client's specification, size, usage, etc).
You do not need to buy every equipment. You can always check if you can rent it before deciding if you really need to have it.
You need to know how lighting benefits your work. Natural light or artificial (strobe or speedlight). Know what fill and bounce lights can do to your image. Photography is the process of capturing light after all.
Photography is both a creative and a technical art. It is better to apply both. But if you are lacking in one, then try to collaborate or hire someone to fulfill that missing aspect.
It is very beneficial to know basic business management, accounting, legal, and marketing. You can always hire people to do it for you, but as a business, it is already an expenditure. Having basic knowledge will make your business go a long way.
Always edit your work. The RAW file contains a lot of information, but you may not like what it looks out of the camera. You can always enhance the sharpness, saturation, shadow details, or even the composition. Post-production is part of your style as a photographer.
Consider making a portfolio. Try to be as cohesive as possible.
