Saw this thread when it had just 2 points and hoped it won't get upvoted since it's just -- sorry to say -- a useless post full of misinformation without delivering any message. I highly doubt the author has enough experience with building relationships, getting laid, get the right one and so on:

Now, since it's on the front page my view. You have two options:

Either you spend your time in your early 20s chasing women and spending all your time on building relationships and getting laid or:

Start at least 5 startups until you are 25 and hope that one of them gets kind of profitable or even better and you do an exit. Starting later is getting harder and harder, you are spoiled by high salaries and laid back office work and suddenly you have a child and it's getting to risky to start anything. The experience you make as an employee hardly help you as an entrepreneur but you need to fail often as an entrepreneur -- every failed startup brings you tons of experience and closer to a successful company.

Back to the girls: if you got successful with your startups you don't have to think about relationships and girls -- you'll send so much self-confidence and they're will be tons of opportunities. And even if you still do startups which didn't succeed you have much more to tell then any office drone. You'll have much more opportunities than those who desperately looking for the SO without having a life or anything to tell. That doesn't mean that you should omit any social life or getting laid while building a startup, it just means don't focus on this, focus on being an entrepreneur.
