hello yamyam welcome to the forum 
There is help and tips all over the forum therefore any introductions just asking for tips are placed into this intro topic 
It sometimes takes time to get that elusive first LD so don’t get too stressed out by the waiting. have you read the choosing your technique and the inks and short descriptions to all new and known techniques in the knowledge base forum?
the biggest tip i can give is use WBTB with whatever tech you finally decide to use and don’t keep swapping and changing. Keep with the method for a while to give it a good chance of working.
Good luck
