Ideally, yes, but like bloodyenigma has said, people who have lost someone tend to be alone. Having lost both of my parents, my life has always felt like a bad alternate reality that should be changed via time travel, and I have been alone for most of it.
It is a less then ideal life when we have to be alone. Same for going without sex, or any other luxury, but then this is a far less then ideal world. You can do it, but that doesn't mean you can do it forever. Years down the road you may look back on your life as a total waste. Do you really want to be an old man, completely alone, on his death bed with no loved ones to comfort you? So maintain a good solitude, but don't give up on meeting people. Try to socialize anyway. Just be distant, take things very slowly, and don't let anyone take advantage of you.
And I agree with Nitrimici, that having people you care about in life leads to greater motivation. I've been unmotivated most of my life. In a lot of matters when it's just me alone, I don't care, but if I'm to be a father and a husband, then I want to be fit, make more money, and be there for them.
Things that will help you be alone:
1) A good imagination: When you can create worlds, characters, especially ones that seem to be alive. When fantasy and day dreaming is so fulfilling that reality is a grim shadow in comparison, merely something to tolerate and escape. If you can fool your mind into thinking fantasy is real it would be even more fulfilling, but you would also become insane and be locked away in an asylum.
2) Books, Music, Video Games, Movies, Art, Hobbies, and Work.
3) Pot: I'm not saying you should do this, just that getting high makes a person content with doing nothing and can sometimes be inspiring.
4) Spirituality: getting in touch with your spiritual side can be very comforting and goes hand in hand with solitude. At it's most advanced levels you may be kept company by angels, familiars, spirit guides, or even your twin flame.
5) Owning a pet, and/or familiar.
6) Religion: I just want to point out how belief can affect you in this matter. Those who believe in an everlasting heaven and that good deeds or suffering make you among the greatest their can easily be alone and brave a life of hardships. But beware, if this belief changes... to reincarnation for instance, then you may see this kind of hermetic life as a waste. If you believe in no afterlife, that we just die, then the hermits life is probably going to be completely unacceptable.
