The main issue with advice these days, thanks to social media and its gurus, is that it all sounds the sane. Which is why I try to draw on stories deliver the point. Stories that we can all read and take away a different perspective. Like all forms of art, it is unique in the view of the person taking it in.
My favorite bit of advice in all aspects one might face in life, work, or art, is trust the process. Each of us have a one of one recipe to that process. We each are at different starting points. Some of us are further ahead, here or there. We each start with different amounts of tools, money, smarts, self-confidence or disadvantages. But trusting the process is more likely than not going to get all of us where we want to go. What isn't talked about enough (in my opinion) is that part of the process is self-doubt Resistance, with a capital "" as Steven Pressfield teaches us. Procrastination. Negative self-talk. FOMO (fear of missing out. We think our idea is dumb. Our goal is too hard to try. And the list goes on and on. That is part of the process. We're human and we must embrace it.
So trusting the process has as much to do with trusting yourself. What is meant for you will meet you it won't miss you and you won't miss it. If you can't quite trust the process, you must start by trusting yourself.
