There are plenty of ways to deal with stress. My favorite way is to live like I learned from Timon & Pumbaa in The Lion King "hakuna matata" :)

I am a type of person who typically strives under a certain amount of stress / pressure. It provides me with an added amount of focus. Although, I will admit that too much stress / pressure will eventually cause my practical side to become over-stressed, or apathetic. If I can't meet a deadline, I become less motivated. If it's going to be close, I'll work vigorously. If I have more time, I'll either coast through the allotted time, or finish quickly and chill.

I do get FOMO every so often though.. but as long as you take a step back and think pragmatically about what caused you to miss out, or what will cause you to miss out, I'm sure that you can come up with a logical reason for missing out (or choose to not miss out).

It's always fun reading your posts!
