It all depends on what you are asking really. Would you rather live without love rather than long to be loved? Would you rather live without a car than long to own one? Two different responses will come out of these two different questions...
If you are asking about something involving people (ie. love, a father-figure, a girlfriend or boyfriend, etc), the answer is what you want will come, you just can't focus on it. People who are focusing on things involving emotion can often run the fine line of coming off to other people as desperate to have those things. Other people are often disapproving of desperation and remove themselves from those kinds of people exhibiting those feelings. Which in turn, isolates you even further. However, if you do things to keep your mind occupied away from that what you want, and you find a way to be comfortable where you are, the thing you want will often come to you sooner than you think.
If you are asking about things in general (ie. cars, a home, etc.) then your answer is that you don't have to live without them. You just need to set realistic goals and reach them.
