Can't fly, or do anything else most of the time.

When I LD, I usually have a hard time flying, or shoot laser beams or any other thing like that. Last LD I had I tried really hard and got off the ground ones then fell down about 3 seconds later. How do you guys make yourselfs fly and such? Is there a trick to it or am I just bad at it?

There is a whole topic about this in this forum and its called “Learning to fly in LD’s”.
