Answer to Question 1

Hot, massive blue stars radiate energy at such an enormous rate that they substantially deplete their hydrogen fuel much more quickly than smaller main sequence stars. You could compare them to cars. A Hummer uses up its enormous fuel reservoir very quickly, whereas a Smart car uses up its comparably tiny fuel reservoir very slowly.

Answer to Question 2

Cloud of dust and gas (nebula)  protostar  main sequence star  red giant  planetary nebula  white dwarf.
