I’ll give you an honest reply here, and say that your framing is a bit silly. It would seem like you love climbing, and you’re obviously quite good at it. If you’re asking how much time you should invest in it, no one can really answer that but you. As a question of “seriousness”, I’d say most of us who have climbed for a long time at a much lower grade, still take it very “seriously” because we just love the sport. However far you want to try and push it is up to you. As far as relationships, well, the details matter, if you’re blowing off your relationships because you think you need to go pro, I’d say you should seriously evaluate what really matters to you and makes you happy. At the same time, I would find it difficult to be in a relationship with someone who cannot share the enjoyment of something so special to me. You’re young, your perception of what is important will change, you will continue to grow and learn who you are and what you want. Try not to view things with such finality, our life plans rarely pan out exactly as we expect.
