I can offer some tips that are applicable to a general audience:
Think about how what you are doing can benefit others. It's far more rewarding to do things for others than it is for your own self-gratification. I often think about how my work can and does inspire others, even if I don't know it. Most people who get inspired often don't like or comment on your work, but it still stays in the back of their mind, and it may motivate some to get started, or to keep going. I was inspired by numerous photographers, all of whom don't know me, but yet still have had a tremendous impact. You don't need to know someone to change their life.
Take inspiration from others, but don't lose your uniqueness. It's important to look at and appreciate other people's work, and it's also important to at least acknowledge and think about feedback other people give to your work. It is, however, a mistake to simply copy what other people are doing. Add your own uniqueness to your work—you'll know you're getting there when you feel an attachment and fondness for something you have created, and when you feel that you have created it or had contributed significantly to its creation. Your work is a combination of other people's influences mixed in with your own splash of paint.
Bad times are the perfect time for creativity. 2020 has been a rough year for most of us, myself included. But I also wouldn't have had 2020 any other way, because even though large portions of my life had crumbled (my relationship with my family has soured, for one), it also pushed me to go out and explore opportunities that I had never previously experienced. The various new perspectives you see the world in and the various new experiences you are able to cherish are what builds you up, and will be what you look back on in the future. They also help shake up the monotony of doing the same things over and over again, and push you to do things differently (or to do different things). Rather than simply waiting and hoping for bad times to end, look for ways to make the most out of those bad times.
And lastly, don't feel discouraged if you feel like you're in a rut and don't feel like continuing, or if you feel that you aren't good enough, or even if you don't feel motivated to do what you thought you loved doing. Life is like that: full of valleys and hills. Some days, you will wake up to find yourself at the bottom of one of those valleys. Just keep going and do not be discouraged. If you need to take some time off, go ahead—there is no shame. Life is a salad bowl full of different ingredients; there is always more to life than just one thing.
