Your truble is the trouble.
You're not tring (trying) hard enough.
As far as a true putting tip...1st figure out distance control. I use avatar movements and assign a value to them based on green speed. Example: 30 ft meter 6 ft per movement on Fast , 7 ft per move for V Fast, 8 ft per movement Tourney. Add or subtract a foot per rise or fall and you're in the ballpark.
2nd look at break...this is where practice comes in. I combine aim with early or late ding (depending on direction of break) I find if you look to Ding your putt you need to allow for more break. Whereas if you Hit early (or late) it tends to get the ball rolling higher into the break right from the start.
It all takes practice. Better equipment can only do so much. You still have to execute the correct shot. Good Luck and enjoy the game the best you can.
