Once they're old enough, find hobbies or projects that can include your children.

Bear in mind these hobbies/projects may not be in your area of interest--in fact, your children will probably guide what you focus on (just don't force them to be interested in what you're interested in). Regardless of the subject, you can make it interesting to yourself.

Once they're grown, you'll have plenty of time to pursue your own interests, and if you're lucky one of your children just might follow in your footsteps.

Mostly your children will grow to love the time you spent with them and you'll be grateful for it when you look back. They'll be happy memories.
