Without knowing you or where you are,i think i can say with confidence that it's partly the lakes you fish,and it partly you.
I fish Waukesha county,I icefish often,I fish hard. many times I'll tote tip-ups and minnows around and never settle on a spot to put them - because many times I've caught two or three fish jigging while a couple tippys nearby never get bit...
Jigging is the way to go in the majority of places. The exception is when fish are scattered and shallow.
That all said,I can remember every time I limited on walleye thru the ice in Waukesha county. Three legal fish is a very good day,one fish is alright....yet there's lakes I sometimes drive to that I expect catch at least 3 legal walleyes.
Work to better learn the waters near home and your success rate will improve - but don't expect miracles.... or spend the gas money and driving time to fish lakes with a better walleye bite.
(edit) One reason I seldom set tip-ups is that I don't want to waste valuable walleye fishing time catching slimers. Many times they're be set right next to a hole with the depth set,waiting for dark.
