Good relationships are more important...than?

Achieving personal happiness is certainly a main purpose of all people.
Without a doubt, it is difficult to find a single definition of happiness or to define its factors because they are variable, with personal perspectives and preferences.
However, (best not used to start a sentence, Nevertheless may be more appropriate)) good relationships with others is a key component of happiness for a lot of people.
And  From my point of view, having good relationships is more crucial than other factors like work or money, because good relationships can help you to get other secondary factors like money, or work.
For example, if you have a supporting family, you can depends on their financial help when you are close to insolvency.
Also Social relationships might be handy in the field of business, they provide you with more chances of finding a good job, or maximising your profits.
Good relationships are also very encouraging to achieve. 
In other words, realising that someone cares of  for you, loves you, and wishes you a good luck gives you hope and confidence to perform hard work, and to do your best.
Also being gentle and cooperative with your colleagues and neighbours, allows you to enjoy a good reputation which reflects favourably on your happiness.
Finally, it is hard to mention all the effects of relationships on happiness, but to say the least, they can turn your life into a nirvana, or a hell.
