Well honestly it just depends on the person how good a technique will work. Just find one that appeals to you the most, and you feel comfortable with. If the technique isn't working after just a couple weeks, don't give up! It takes time and you need to stick with a technique. The techniques with the highest success rate probably are DILD and MILD. Like I said it just depends on the person, though.

Good tutorials:

DILD:
-Puffin's SAT Technique
-All Day Awareness by KingYoshi

MILD:
-Naiya's Simple MILD Technique

If you are thinking about MILDing it is recommended you do it with a WBTB. You will have a better chance of becoming lucid. So just set an alarm about 5 hours after sleeping, and MILD then. If you don't want to use an alarm, just drink a ton of water before bed so you will wake up naturally in the middle of the night. Good luck! I hope you start getting lucid soon
