Life advice I'd advise to one of my younger family members.

Don't take criticism so hard. You need to remind yourself that this family's roots are based at slagging. Don't dish out what you can't take. That's about it and nana and grandad makes a good roast dinner. If you really want to do something do it no matter what anybody else says about you. 

Ps. If someone says you're not normal don't bother with them, I'd rather be my weird self than a fake "normal" person.
