You need to prioritize how you spend your time. This is not a one-time exercise. It's an ongoing process.
You look at the things that you do in a given day, week, month, and year. You see how they benefit you, your family, friends, community, and society. You weigh that against your goals and happiness. You make little adjustments to how you spend your time.
Concreted example: I like gardening. Not any gardening, but growing heirloom tomatoes in particular. They are a finicky bunch and are often not the easy-to-grow varieties. This is OK. I fail a lot. I need to dedicate more time to this in order to succeed. People tell me to not try growing from seeds, but get some seedlings and start from there. That would not satisfy me. Unfortunately, I have other things that I value greatly so I decided that after this season, I will put growing tomatoes on hold. I'll get back to it once some of my current priorities pass and I have more time.
Over time, your life will begin to look more and more in tune with your goals and expectations, and you will be a happier person.
Fill in your own details and don't try to copy off of others. Everyone is different. And don't try to grow heirloom tomatoes with kids, a full time job, a side business, and an active social life--the day is too short for all of that.
