When in doubt, hold on to your altitude. No one has ever collided with the sky. You know you've landed with the wheels up if it takes full power to taxi to the ramp. Stay out of clouds. The silver lining everyone keeps talking about might be another airplane going in the opposite direction.
Good judgment comes from experience.
Unfortunately, the experience usually comes from bad judgment. It's always a good idea to keep the pointy end going forward as much as possible. Keep looking around. There's always something you've missed. The three most useless things to a pilot are the altitude above you, runway behind you, and a tenth of a second ago.
