I say, either just work on something else, or take a breather and enjoy yourself! Once I had this mindset, there have been so many situations where I've found myself hitting myself against a wall.
Although I'm not 100% finished and still running into roadblocks, my frustration and mentality have improved and I hope this can help others so that their projects will not fall to the mind. You've got this!
If you’re doing something and it’s not working, it’s best that you take a break at that moment instead of going crazy over it and being angry that things are not working, just chill out and when your mind is in a relaxed state, you can get back to it and start working again. And another problem that a lot of people face, and that’s after their project is done, is funds and ways to promote their projects, I think they should always plan ahead, so not to find themselves in a tight position later.
