Yes, I've have had 3 different breakfasts throughout my whole life.
First one in childhood was nothing, just because I really didn't understood the importance of eating back then.
Second one was the exact same brand cereals for 15-20 years.
Third one is current one. Probably the best one. Quick oats+yoghurt+protein powder. Easy to make, easy to eat, nice macros for the begging of the day.
