Look yourself in the eyes (a mirror helps) and repeat 100 times:
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
“I will get a grip”
Ah, f… it! 10 times will have to do.
