You're doing fine.. it's not easy lar so this is normal. Ok let's recap on the fundamentals:

1. Make yourself to be the master/leader of the pack.

You need to establish that you are the leader and it must listen to you. Take him to a field or yard, preferably without distraction. Use a long leash.
Now walk around. Don't look or acknowledge him. If he moves away or do other things, tug him and drag him. Don't shorten the leash. Leave it long. Don't look at him or call him.
Just walk and keep walking around.

Secondly, when you are with it at home, don't sayang don't praise don't do anything with it. Unless it does something right. Just ignore it.

Also, if you're watching TV for example, put it on a leash and bring her to the foot of the couch on the floor beside you.
Watch TV, etc and ignore it.

Do the above, and you'll establish yourself as the leader and it must follow you and his existence depends wholly on you.

Remember, ignore ie no calls, praise, pet, eye contact, nothing. Bad things - ignore and if needed pull leash and bring her away. Good things, maybe a praise but that's it.
Just do the above first and you'll find the other things will come much easier.
