I managed it!!!

For two reasons:

I woke up and did recover my balance:
I realized that, if it was money i needed, than i should start doing some JOBS. Wich i did. They pushed me a couple levels up, but that's all right. Jobs started paying better money and made reload my health until i found this other GREAT help.

I found a totally DUM player, 3 levels ahead mine that putted all his hability on health. Wich is an HUGE mistake.

Here's what happened:

I am now:

Level 17
105 Health
70(+49) (because i have ALL weapons available) Strike
35(+49) (because i have ALL vests available)
Gang 455
Weapon: 22Gun And bullet proof Vest! (Plus all the others, bellow)

This guy is:

level 18
500 Health
15(+12) Strike
15(+16) Defense
Gang 8
Weapon: Crowbar and knife proof Vest.

In result in spite his 500 Health, every time i click the strike button i make him like 300 wounds and suffer about 3 or 4.

So, on a full loaded health dose, i am now able to fight him and win 6 or 7 times per dose!
3 Points of Power each! You do the math...

So i am now fighting on the 22 gun, the bullet proof Vest, all the other previous weapons and i have my first business Built!
