welcome!
I would highly reccommend a dream journal as well... it has greatly increased the vividness, length as well as the amount of dreams I have had and it is a lot of fun to read it after a few months and see what you have been dreaming. Also it helps to discover dream signs.
I also want to add that of course it's not to early to ask those questions, but always try to be patient. If you are consistent, patient and keep trying then you will surely have more LDs soon.

Happy dreaming to you too!
