Is it bad to be a follower instead of a leader?

Ofcourse not, becoming a leader or a follower is just fine, there's nothing bad with either of them at all! You could be a leader who makes the plans and lead people where and how to go, or you could be a follower who helps with the work and support each other, you could be whichever you want and there's nothing to be ashamed of, I've once become both and what I've saw in the most efficiency is cooperation, its completely okay to be what you want and can, you can go and try something new, but you can also don't have to push yourself pass your limits if you think or know you can't, be whoever you want, it's fine! It is for you to decide.
