Hello,I just created my first Unarmed character.My build was based on Joe Metzger build I found in random unarmed-related post.But I have very difficult time on leveling with this unarmed character

I dont know where to start,sometimes i read other post they could reach level 21 in days but me to reach level 2 took hours

Here's the build if didnt know :
ST :10
PE : 1
EN : 10
CH : 1( I have no need to worry,cause I unarmed need less equipment and I also can get stuff from other character)
IN : 4
AG : 10
LK : 5
Tagged Skills : Unarmed,FA,Doc
Optional Traits
-Small Frame
-Heavy Handed
I also had many problems such as,which skill I must increase first?What is the most efficient/fastest way to kill enemy depend on my build?Where and which enemy are good for starter?If can

are they someone has any tutorial video for this?I really appreciate for every helps given so we can share altogether

(FYI,before I created this character I created other unarmed character with this build 10/1/8/1/5/6/10 traits small frame.I only kill ants,brahmin,dogs but I rarely can kill them cause they always outnumbered me.I can only reach to level 2

)
Yes, I know I'm a noob.
