In my talk I will present results from LCDM simulations and SAMs on the various different stages that massive galaxies go through on their way to maturity: At high redshifts z~6 they go through a growth spurting phase driven by high gas accretion rates and possibly triggered star formation. This episode is followed by a period in time around z~2 when massive galaxies grow in 'equilibrium' with their cold accretion rates, before they turn to a phase of growth mostly via mergers. I will highlight each of these phases and discuss their consequences on the properties of galaxies.
