It's not difficult. I don't know who told you that but it is a lie.
Outstanding people can also be your doctor that every time you get sick, you go to the clinic and she/he takes care of your health. Those people are outstanding.
And yet, If you go on and ask them "Hey are you rich and famous?" most of them will say no, but nevertheless they are there, helping you get better. For me, that's an outstanding person.
