You'll get two of these, never all... It's the way it is.
You also get 2 out of 3. If you get all 3 > you're lucky indeed!
1. Common interests!
2. Great personality!
3. The perfect phisique!
So if you're wondering whether you'll ever find all of this - it's on you to decide wether ALL of these are indeed that crucial. If they are > wait for that special person, but also don't just sit there - actively look for them. If you are alright with someone who doesn't fit the bill in its entirety, then I say be happy with what you have. It's up to you to decide and act accordingly.
