New player jungler

Hi,

I'm a newer player of League. I have played several matches and really enjoy Blitzcrank. After picking up a few other champions, I was forced to play in the jungle in a match yesterday.

I have watched several videos since I started - but, wasn't sure how to do the jungle right.

My questions are:

1. Is there a set path that I should be doing the jungle in?
2. Should I go into the jungle on the enemy side?
3. Can any character jungle?
4. Can Blitzcrank jungle well?
5. What is the easiest jungler to survive with?

I played Shaco yesterday, who I thought looked cool so I wanted to play him, but I really struggled to kill minions in the jungle.

I appreciate any constructive feedback!
