The difference between you and the people who are successful and have your dream job is that , they are doing it.
Don’t give yourself excuses like, “well, they are rich”, “well, they went to school”, “well, they are pretty”, “well, they are this or that”.
When you start doing it, you are instantly on the other side of the door, among do-ers. Your doing-ness does not need to be perfect.
You CAN still try to be as good as you can. I recommend that.
If you don’t know how, the best way you can learn a job is from the people who are doing it.
I am absolutely sure, you will learn more that way than if you took a class about it. Whatever the subject is.
