Sharing experiences of raising 2 children - how to avoid being "overloaded"?

I am currently raising 2 children of different ages, each with their own needs and personalities. Sometimes I feel like I don't know how to balance: taking care of the older child's studies while taking care of the younger child also requires a lot of time and patience. I would like to ask parents in the forum: When you have 2 children, how do you divide your attention and time so that both children feel loved? Is there any secret to limiting comparison or jealousy between children? I really hope to hear more practical experiences from everyone, because I believe this is a problem that many families are facing.
