<prompt> Human: My situation is fortunate in that I live with family. Pertaining to the future, I intend on just saving. No kids, relationship or anything like that.That being said, I work 45 hours per week right now, but Im thinking of bumping it up to 50 for more OT. Some questions: How do I stave off burnout? Is a 401k worth starting or am I better off just putting cash into savings?Thanks!  <response>: 50 hours a week, no relationship, living with family, I dont think thatll cause that much burnout. Might be a US thing, but I feel like 50 hours a week is pretty common, and most people can balance that with family alright, so you should be in good shape unless its very physically taxing. 50 hours of an office job is fine, 50 hours roofing, kill me now.
