]Keep in mind the above can be said for nearly any game of skill. If you want to be at the top of any sport or activity you need to invest quite a bit of time in it. What's really important is what sort of positives you derive whether it be fun, social, physical, etc. If it was all about winning very few people would continue with such activities after 30.
For instance I continue to play hockey all year despite the fact I would get absolutely destroyed by a Junior B player.
