"Alone we can do so little. Together we can do some much." Helen Keller
I have found over the years that when I try to do things...personal or professional completely on my own it can work out...but not always. I will not say that including others guarantees a positive outcome BUT I do believe the odds increase.
Gathering feedback, opinions, ideas from others typically helps me decide the right course. I enjoy working in teams. Again, it is not without its complications however I have found the team experience to be more fun as well as more rewarding whether the outcome is successful or not!
When it is not...I also find it more helpful to be working with a team. There are more insights into how to improve post the issue or challenge. There are also more people to commiserate with frankly as it is a shared experience.
Folks sometimes feel solo is better and there are many different motivations for that feeling...too many to list! I challenge you if you are one of those individuals...move outside your comfort zone and ask for help, advice, a review of your project or presentation and see what happens. Maybe nothing ...but maybe something incredible!!
Anything is possible!
