6. Boost skills like Driving and Stamina with expert road maneuvers and triathlons. The better your characters' skills, the easier that completing heists and other missions with maximum efficiency will be. And you WANT those heists to go off without a hitch--perfect execution leads to significantly higher payouts and can help compensate for AI crew members' failings.
7. Don't risk losing money to the perils of Los Santos. Save your tricked-out car in a garage ASAP, for a rainy day, lest an accident or explosion leave you out hundreds of thousands of dollars.
8. Off-road races, midnight street races, and sea races are your friends. Use these opportunities to kill two birds with one stone, raising your Driving skill and earning cash at the same time.
9. Watch out for Gruppe 6 security vans; they carry thousands of dollars of cash in the back, so run one off the road, or shoot at the van to get the security officers to come out. Then, hit the back doors with an RPG or drive the van to a gas station and blow up the tanks. A suitcase of cash awaits.
10. Hang around ATMs, wait for an unsuspecting passerby to make a withdrawal, and rob them.
