You can't take people's opinions personally. Usually what people say about it is a reflection of them own issues.
I really don't think life is about the I-could-have-beens. Life is only about the I-tried-to-do. I don't mind the failure but I can't imagine that I'd forgive myself if I didn't try.
Keep going on hikes, keep having your friends in your life, keep that downtime sacred as well because as hard as you work in any job, it's really nice to have the relaxing de-stressors. Stress is the worst thing. That's the ultimate demise of any good thing.
