Just do not fall for the myth that the right guy(#) or the right job will just come along. You have to go and find it. The clever part is maximising the surface area you have "out there" whilst keeping a quality reputation.
I suggest the following:
1. Decide roughly your ideal company / man (see (#) below)
If you cannot write a paragraph about the ideal that really knocks your socks off, then you do not know what you want. This is then the time to sample many different types and determine which suits you best.
2. Be aware of the local landscape - Angellist is good here as is OKCupid. However nothing beats meeting people face to face. Go to networking events. (Both kinds)
Whilst this may seem a little light hearted please remember this one important truth:
The best dates / jobs will come from mutual acquaitances able to connect you both. So this means expanding the people whom you know - spending all your time in one office with one set of people will limit the fish you can catch. So attend networking events, of both kinds, and remember its a sellers market.
Its your twenties. Have fun.
(#) broad assumption that you are hetro, but if not its still a sellers market it seems.
