Fear can tickle your brain until it crescendos, but if you learn withstand the sensation, you will be numb to it.
Keep in mind, you will not succeed if you do not try. Give what you are doing a chance. I know it’s easy to give up and think success won’t happen. But the truth is this; sometimes success takes a while. If one idea is not working, try something else. Eventually, success will pick up speed.
I am going to pick on writers/authors. They spend many many hours writing their books. At the end of it all, when they publish it, there is marketing to do. If you are a self-published author, you do much of the marketing yourself. My advice, if this is you, learn about how to market your book(s). Maybe you already know. Great! If you have a publisher, they do the marketing for you. If this you, great! Everyone else mostly does it themselves. It can be discouraging at first because not every marketing strategy will work. Here again, you will not succeed if you do not try. You will not figure out what does if you do not try.
What do you want to learn? What interests you? Do you ever know all there is to know about what you do know? Lifelong learning. That’s where it’s at. One of the areas that interests me the most is writing fiction. Even though I write a lot, doesn’t mean I know all there is to know about it. I am always eager to know more. So I look at what others do and take my cue from them. I can use that to come up with my own tricks, so can you. I enjoy reading books about writing. Even though I am published, I still yearn to know more.
But, know this. Take what you learn and make it your own. What works for others might not work for you. I learned this lesson early on years ago. I found that a combination of methods works for me.
Whatever it is you enjoy doing, continue to learn about it. Be a lifelong learner of what you do. Continue to upgrade what you enjoy.
