Should I lift more weight each time I go lifting?

Should I expect or strive to increase my weight every time I lift? Like say, Monday I do dumbbell incline at 55lbs each hand and then Wednesday or Thursday when I go again, I should try and go up to 60lb dumbbells.

By the way, I'm 20 years old and I can do about 55lb dumbbell incline. Is that pretty good?
