Step one, making a profit, which you never knew you had!
After finishing Tutorial Island, bank all your items and go straight to the Grand Exchange in the large town of Varrock.
Next, withdraw all your items in notes and sell them in the Grand Exchange, you will be amazed with how much money all the stuff you sell is worth!
Next, buy full iron and an iron scimitar.
Step two. The weak can make you strong.
Now go to the dummies in Varrock and attack them, they will get you attack level up to level 8!
After that if possible buy a Steel Scimitar.
The weak can make you rich (levels 3-25)
As crazy as this seems it can make you rich!
Go to the chickens in between Lumbridge and Draynor village.
Start killing them (training up your attack level) and collecting all the feathers and bones after you kill them. (If you want to level up quicker only pick the bones from the chickens you have killed)
Once you get 20 Attack you should check how much gold pieces you have got. Your combat level will only be 10 or 11.
I am at this stage right now and I am amazed that I already have 27k worth of bones and 7k worth of feather (I am talking about gold pieces, not amount) I have got 233 bones (or was it 322? and 1910 feathers)
Now go to the Grand Exchange and sell as little as you have to, to buy a Mithril scimitar!
Now start training your Strength up to level 40.
By the time you get level 40 Strength you should be level 25.
Step three, big, bad and rich! (25/30, whenever you choose)
Now if you have decided to proceed then be prepared for anything!
This is where you delve into the darkness; it is time, to face.... the HILL GIANTS!!!
Start and keep on training your Attack level-to-level 40 by killing the Hill Giants.
DO NOT pick up anything else from the Hill Giants except Big Bones and Limpwurt Roots.
Now once you get to 40 attacks you have two options: Train your Range up to 40 or train Strength to level 70.
Congratulations, you are now a level 60 or below and if you sell all you items you will see that not only are you an amazing warrior but you are also a really rich player!
When I say amazing warrior I mean, you can hit 19's with a rune 2 Hander and an Amulet of Strength! And, if you want you can get your prayer up to 31, then you can use Ultimate Strength and then hit 22's!
