Does lucid dreaming become easier the more time that you have spent being lucid? Or have you just had to find a technique that fits you?

I've only been at it for 6 weeks and it felt easy to become lucid within the first few weeks having 5 lds and many dreams close to being lucid. But lately I have had a hard time even when obvious stuff like a dream sign pops up, I even dreamed about going to a lucid dreaming school to learn and diddnt question it once.
