Is it ok that I am single at 24?

I am 24 and haven't really had anything serious with a girl before. I was very ugly as a teenager and nobody showed interest in me. I'm getting a lot better looking now. Also I'm just really busy right now. Im working a full time job with 77 hours weekly and finishing my degree and am set to go into the active army as an officer next year. Are there any decent single girls left?
