I fell into modelling, it wasn't something I went looking for or considered myself appropriate for (size or other wise). However, after a favour to a friend, I found an enjoyment for it and it's grown from there. It wasn't as easy as movies/shows  made it seem, to say I was surprised at how much work it can be, is an understatement.  It can be both physically and mentally tiring, not to mention knowing how to take care of yourself and not let the judgement of others put you off.

If I had to give a tip to someone wanting to give it a go, it is learn about it before you start, decide what you want to do and stick by your decisions.
