Ask for help
Make it a goal to connect with one person, outside your family, every day. One way to do this is to ask for help.

Here’s how:
Set a specific goal each day to ask for help. Over time, you’ll have made it a habit.
Plan each morning what “the ask” is going to be and who it’s going to.
Put a reminder in your calendar with an alert so you don’t forget.
Start with your family. You can practice on them with simple things. This has at least two benefits: the first is that it’s an opportunity for you to ask for help and the other is that, if you’re a parent, it gives your child a chance to learn something new. You might already know how to do what you’re asking (but they don’t have to know that!)
Practice on new and different people throughout the week: Family, friends, coworkers, store clerks (after all, they’re there to help!), and for bonus points, complete strangers.
