This type of question, depending on the area in which it is done, will have two possible answers.
Before answering it in business, let's remember our time at school, when the teacher sent us to make an exhibition for the house in a group of 4 people, where you had to carry a poster with information, a printed work and most importantly, the points Divided and learned by its members to explain the subject.
Was group work better at work alone? It depends! Since if all the members collaborated and did something worthwhile, obviously the most convenient for everyone was the work, the points were divided, each to his right and ready! The exhibition would be complete and ready for the day he played.
But, if you knew very well that the companions with whom you had to do that work were those who did not do anything, they preferred to leave everything for the last hour no matter how the job came out, there is reason, more than enough, to say That it is better to work alone, since you know yourself and you know you can do that and more. And when you know that other people do not work like you and are deficient in ordering a mandate, that's when you decide to work alone.
Now let us ask this question in the field of business. Obviously also can be answered in both ways, however, already in this world, where we are already professionals and we are together fighting for the same goal, money, here the rules change a little, it will not be something as simple as an exhibition from college.
When you start a business you have to think: can I do it alone or do I need someone else to do it?
The answer always for this is to try it first on your own, since I know very well that we all have the ability to get ahead through our own means. Make sure that if you have someone by your side helping you in your business, keep in mind that that person is not "toxic" or instead of a help is a block.
Many times we will start a business by ourselves, alone. However, there will always come a time when your business is so big that your own hands can not afford to keep it anymore, and that is when you need new help.
Always look for capable and professional, and above all responsible, people who occupy every place that is needed in the business for the company to grow.
That is why I will tell you, teamwork is better, as this will help every day is bigger and better as they can cover more and new areas that if you were alone, you would not be able to do as it is not your experience or you do not know how to do it, this is where the team arrives so that all its forces unite and form a single.
