What has been helpful for me is the group of friends I usually hang out with. They are all highly intelligent achievers and as a result, there is always this peer pressure on me to do better. We are close like brothers and are supportive of each other though. That turns the pressure into a positive nurturing force.
This is one thing that I've struggled with during the pandemic - I realized how much I relied on friends/classmates/colleagues to motivate and challenge me. It's just not the same over Zoom unfortunately.
