Take a CPR class together.
Emphasize importance of staying certified ( or making a habit of watching an online course every year on the same day, like the day after Thanksgiving or something like that.
Imagine a hundred different lives. Try a dozen of them. Fail at most of them. That’s part of what your twenties are for. Challenge yourself. Challenge your assumptions. Change your perspective. Grow.
When you meet people in an intimidating situation, like a job interview, etc. An easy trick is to imagine them as they were in kindergarten. (Don't talk to them like they'r 5 year-olds! But relate to them on a human level. We're all human - filled with talents and fears and insecurities. No matter how "important" or "unimportant" our station is.
When you begin dating it’s all butterflies and moonbeams. Eventually you’re going to do or say something that hurts the other person and vice versa. For that matter, eventually you’ll disagree about something. It’s VERY important to consider how they handle it. Nobody is perfect, it may not be pretty but it had better be civil. If not, don’t think for a second that they will change. Get outta there.
Staying calm while under pressure or when you could scream in frustration - that is most of the battle. Sometimes the fact that you stayed calm qualifies as a win.
Avoid commenting on the number of children someone has (or doesn’t have.) Its none of your business to ask why a couple doesn’t have kids or remark if they announce they’re pregnant with their 7th (other than to say “Congratulations.”)
Kids who are a little different (maybe they make funny sounds, look different, or aren’t able to talk or walk very well, etc.) Remember that just because they might be different, they are never “less than.” Their feelings matter as much as yours. They like to play as much as you. Their families love them as much as your family loves you. Include them as much as you can. You could end up making a great friend!
Stuff will happen and you’ll think “I can’t get through this. I can’t go on.” In the moment it really feels that way. But ...You will survive. You’ll find a way. Never give up on yourself. I never will.
