Basically subj.
The skills and what I found so far is:
- Stamina: just run, sprint, cycle, swim, whatever. Just move and it will grow(not that fast though)
- Shooting: personally I found shooting range to be a really fast way to improve your shooting skills
- Strength: fist fighting
- Stealth: performing stealth kills
- Flying: probably just flying, didn't bother about it yet
- Driving: got the most problems here. Playing as a Trevor I can't get past 1.8 or 1.9 bars(which is 36-38%). Drove for hours around and still can't get it any higher
- Lung Capacity: staying underwater for as long as possible can very slowly but surely increase your lung capacity
Am I correct with the ones I know? And what would you recommend for the other ones?
