Any help would be appreciated

My father was taking me to Detroit Race Course when I was eight years old. I was able to read the racing form and he really developed my passion for horse racing. Well after four years in the service, getting out and establishing my career and starting a family I started to renew my passion for handicapping. I feel that handicapping has passed me up. My father was big on Daily Doubles, Trifectas and straight WPS wagering. I have been trying my hand at multi-race wagering but have little sucess and when I do build a ticket I have a hard time developing a reasonably priced ticket. Of late I havent been having much sucess and my confidence is wavering.
Any advice on money management, how you approach multi-race wagering, how many cards you attempt on the day you choose to wager and etc... would be greatly appreciated.
