They aren't gonna understand it until it speaks for itself.
Many people obsess over whether or not people believe in them.
1. Why does it matter?
It doesn't.
Literally at all.
2. What have you honestly done in your life to give people a reason to believe in you?
Being born doesn't count.
What you should be concerned with is if you believe in you.
...and the only way you can do this is by proving to yourself over and over on a daily basis that you can trust yourself to follow through on exactly what you said you would.
That's all that matters.
Execute day in and day out and eventually the results you produce will be undeniable.
You'll believe in you.
So will they.
Only then will you come to realize what I'm telling you now is truth.
It's irrelevant.
