i cant catch walleye! help!!!

[wolf man]

hey guys, ive never caught a walleye , ive targeted walleye several times this year. ive done a bit of reading on techniques and i have had no such luck.im not sure what im doing wrong. probably a combination of everything.
i wanted to go back to Lake Hopatcong with an idea of how to catch them since what ive read hasnt worked yet. what is the best time and what is the best location to target them there? live bait or lures?deep or shallow? please pm me or let me know. or if you are willing to go out with me on my boat and teach me, let me know. thanks in advance for any help!
