I've had this feeling too. Ever since I was little.
It's a heavy thing to carry with you but a grand one at the same time.
As much as it might sometimes limit you from experiencing your happiness, which by the way, I think is just so overrated and completely messes with ones point of view - it's a good reminder that keeps you going.
I've had issues with this feeling that I am destined to succeed. That I am destined for good things in life and wealth. It might sound narcissitic but let me break it down for you.
What I've been experiencing in the past years is actually a mixture of perfectionism and self doubt at the same time.
I've left school and decided not to continue my studies as I have such a strong intuition that I will do great in life - and that comes with great responsibility, especially if you don't want to be stuck in a dump, working 8+ h a day for a minimal wage.
But how to actually succeed and justify your intuition is a lot of hardwork. Myself - I am an artist. I paint, write and do music.
I chose to be good at those things, I was never talented. I wasn't priveleged yet some might think so.
It's a lot of hard work and skill. Skill.
I think the only way in life to fully fullfill yourself is by skill.
To constantly improve yourself, improve what you have chosen to be your talents, improve your daily habits and commit.
For example, I decided to write a novel this year. I commited. I write everyday and the improvement and growth of my work is amazing.
Same goes for painting…
You just have to figure out, what is the thing you are destined to do. What is the thing that makes your soul tingle when you think about it. I know it's complex and you might end up with 500 unfinished projects but pick the one that's the closest to your heart and drill it.
Work on it everyday. And don't strive to be good, strive to be the best at what you do.
Those book ideas that you had? Just do it. Sit down and just write. And remember you don't have to be good at what you do in order for the finished project to be great. Especially when it comes to writing.
Just write for now, get the ideas out. You have to be constant thought and the issue with me was my perfectionism would always interfere with my projects - oh this is garbage, this is so bad, no one can ever see this.
Change your mentality and do things for yourself.
Start writing your book, with time you will improve your writing, read.
Read a lot to get the hang of sentence structures, read about novel writings, guides…. Or just trust your gut - it knows best.
But whatever you do - stick with it and the results will follow.
The feeling of being destineed for greatness can benifit you in so many ways. Believe, work, achieve and the rest will follow.
Good luck fella!
