Can't survive the night

If pure survival is all you're looking for, you can almost always survive a night by digging a 3x1 hole, jumping in, and replacing a dirt block above your head.

Be careful of creepers in the morning.

Edited to Add: If you can't produce a light source, then most attempts at nighttime productivity are pretty much doomed. If you can be productive indoors, then there is a limited range aroudn a player (24 blocks) that monsters can't spawn in, so a 25x25 floorplan building can be used without a light source. Be careful about this though, if you leave this building for any reason before you have lit it, you might be coming home to a ambush.

One of the best things i could suggest is building a house that's 5/6 blocks ABOVE ground level, Using ladders to climb up to it. That way any mobs that do spawn and come after you during the night can't shoot through any gaps you have to leave due to lack of resources/time/ect.

The very first thing i ALWAYS do when i'm playing survival is cut down as many trees as possible and gather plenty of stone, Always keep a block or 2 of the logs (not turning them to planks) so you can put them in the furnace and create charcoal, That way you can make torches without having to find actual coal which is often difficult to find at the most inappropriate times.

Plus you can make yourself a decent sword then just incase you do have to defend your home
