I am a busy young professional, I have my life together but I realize that I don't have hobbies. I like investment and travel, that's about it.
Most girls I know have their girly hobbies that I find unbearing. I also don't like any sports or golf, fish etc.
What should I do? I like to develop some hobbies but most of them don't interest me.

Just accept that you're a workaholic.
No one "needs" hobbies, they have them because they are doing something that interests them.

Well a hobby can be almost anything really, be it time consuming or not. Even if you don't have time to build the Empire State Building out of popsicle sticks you could still try various other things that aren't as time consuming. For instance, collecting snow globes from your travels or doing crossword puzzles on the plane/train.

Just accept that you're a workaholic.

If you really want hobbies try things that are related to what you enjoy. You like investment and travel how about reading books on those two topics and that could lead to more. Look at why you feel that you need to have hobbies? It isn't a requirement for life that you have hobbies. If you are doing this just to get a girl, know that there is someone out there who will enjoy you for who you are and not worry about how many hobbies you have. Embrace you!
